Simple game. Next poster has to guess what quote the movie is from, then they post a quote of their own and the following poster must say the name of the movie that that quote is from.
For example if I were to post this:
"I'm just a broken down piece of meat, and I deserve to be all alone."
The following poster would post the name of the movie it's from:
"The Wrestler"
Followed by posting another quote of their own.
Ok, simples.
I'll start:
"Hamburgers! The cornerstone of any nutritious breakfast!"
