Though they know a lot about each other, Biff and Emmett Brown are never seen interacting in the films — only in the animated series and ride. However, Doc has tangled with several of Biff's ancestors, such as Buford Tannen.

In addition to his lobbying of legalization of gambling before the California Legislature Biff also spearheaded a constitutional amendment to repeal the 22nd Amendment to the U.S. Constitution. Biff was apparently an admirer of Richard Nixon, whom by repealing presidential term limits, he had helped get elected to at least four terms as President of the United States. Biff had presumably altered the timeline by either bribing to cover up the Watergate investigations or resorting to outright murder. President Nixon had plans (at least as of 1983 while seeking a fifth consecutive term), and leaving the Vietnam War unresolved as of 1983, which meant Biff's ways has affected the entire world as well. Though he was promoted (at least by himself) as "America's greatest living folk hero", Hill Valley in 1985A had become a center of crime, corruption, prostitution and gang warfare — which was not surprising really, since Biff also had control over the Hill Valley Police Department. This is a crime against humanity. In 1985A, Doc discovered the top of Biff's cane and the receipt for the sports almanac in the DeLorean, from which he deduced Biff's theft of the time machine. Hey, McFly! I thought I told you never to come in here. Since you’re new here, I-I’m gonna cut you a break, today. So, why don’t you make like a tree and get outta here?” Dr. Emmett Brown: The way I see it, if you're gonna build a time machine into a car, why not do it with some style?”Kidadl provides inspiration to entertain and educate your children.

In an interview with the official BTTF Club magazine, Thomas F. Wilson speculates that Biff's grandmother was probably the primary reason Biff grew up to be such a jerk. He also claims Biff's signature "Butthead" and "Hey, McFly" quotes were mostly his ideas. The almanac contains an incredible amount of detail, including college football games played on November 12, 1955, and the results of horse races on Biff's 21st birthday in 1958.

On October 21, 2015, Marty McFly, who had time traveled from 1985 to 2015 in Dr. Emmett Brown's DeLorean Time Machine, happened upon the book and fantasized about knowing the scores before they occurred to make money. When Dr. Brown found the almanac, he immediately discouraged Marty from using it or the DeLorean for financial gain. As Doc was about to place the book in a mobile trashcan called a Litter Bug, he saw police officers Reese and Foley investigating Jennifer, whom he had earlier tranquilized and left in an alleyway. After the officers went away, Doc threw the book into a traditional stationary trashcan and walked off. Unbeknownst to Marty or Doc, Old Biff Tannen had been listening to the conversation all along, and he had discovered the existence of the time machine. However, Biff followed Doc and Marty to Hilldale in a taxicab, then stole the DeLorean while they were distracted in trying to rescue Jennifer from the future McFly residence.Whether it be funny Marty McFly quotes or any other Marty McFly quotes, they all are still enjoyed by fans. Here are some of the best quotes from Marty McFly, quotes that are hilarious, right in this list for you.

Biff like the rest of the Tannen family bullied people to get what he wanted. It is fair to say he wasn't intelligent during his youth, as he constantly got his metaphors incorrect and he had to force George to do his homework for him to pass his high school classes. He had a crush on Lorraine Baines and referred to her as "my girl", and continued to take an interest in her even thirty and sixty years later. Lorraine did not return the sentiments. Our Values: We strive to work with respect, reliability with oomph, and craftsmanship, and also to promote the democratization of sports data.The film's writer, Bob Gale spoke to this question in a Q&A session for the Official BTTF magazine. The short answer is that his pain was caused by having changed the future enough to erase his own existence. Work at Sports Reference: We are a profitable, bootstrapped, remote-first company that offers competitive salaries and outstanding benefits. (More) Old Biff thinks he's talking to Marty Jr., and tells how Marty McFly Sr. had his own life completely flushed down the toilet. Biff's father appeared to be a slightly tougher parent in this timeline, now admonishing Biff to show respect for his stepmother, which may have mellowed Biff's rough attitude somewhat.

The Grays Sports Almanac had been released on December 31, 2000, marking the end of the 20th century. Biff was reluctant to believe "some old codger with a cane", but eventually came to believe its validity. Using it as a guide for betting, by 1985 he became a celebrity and built a financial corrupted empire in an alternate reality, where he secretly murdered George McFly, married Lorraine Baines McFly and ousted their son, Marty. On October 26, Marty, Doc, and Jennifer returned to 1985 and found themselves in an alternate reality. Doc discovered the items Old Biff left in the DeLorean. Doc explained Marty that the almanac caused all this and urged him to ask Biff, now his stepfather, the time he got the almanac and remedy the event. By 1985, Biff's marital status is unknown, although Biff had a grandson Griff by 2015, indicating that Biff had at least one child by 1985. (According to some sources, Biff had a son, Biff Jr., who, it is suggested, owned the Cafe 80's). He may have also had a daughter named Tiff Tannen, short for Tiffany. [1] Given that newspapers from the future change as the timeline is altered (due to the ripple effect), it's conceivable that such an almanac would always be accurate. And possibly, the book itself experimented the ripple effect if an event registered there happened in a different way on the alternate timeline.Wait a minute doc. Wait a minute Doc, are you telling me you built a time machine out of a DeLorean?”
