Back to the Future’s’ Biff (Tom Wilson) has a post card for you

You know him as jock-bully Biff Tannen from the wildly popular '80s-era "Back to the Future" film franchise.
Actor-comedian Tom Wilson, who played Biff, is painfully aware of this fact.
Presumably tired of answering the same old questions from fans over the past 27 years, Wilson has written a fact sheet in the form of a post card enlightening us to all those pesky BttF inquiries he gets.

Here are a few gems:

• Michael J. Fox is nice. I'm not in close contact with him. Christopher Lloyd is nice. He is a very shy man. Crispin Glover is unusual, but not as unusual as he sometimes presents himself.
  
• The hoverboards didn't really fly, we were hanging by wires from a crane.
• The manure was made of peat moss, cork, dirt, and a food agent that made it sticky.
• Among many improvisations on the set, I coined the term "butthead," as well as "Make like a tree, and get out of here."

And if that's not enough, Wilson has also written a comedic song about the trails of answering the same questions for decades in a row, called, you guessed it, "Stop Asking Me the Question."
