My friends and I recently had a BttF marathon, which was awesome. We intend to have another marathon in the near future, but this time we want to do it as a drinking game. I was wondering if you guys have any suggestions for cues. Here's what I have so far:
Whenever someone time travels.
Whenever someone says "This is heavy."
Whenever someone says "Great Scott."
Whenever someone calls Marty "chicken".
Whenever a picture/newspaper changes.
I'm sure there are a ton more that could be added. Any ideas?
