I mentioned doing this on Twitter recently, and at least one person (Mark!) was insane enough to agree. The basic theory is that you watch The Boondock Saints, taking a drink of alcohol for several events.
You take one drink...
...whenever someone says fuck.
...whenever something religious happens.
...whenever someone drinks alcohol.
...whenever someone discusses rope.
...whenever Smecker (Willem Dafoe's character) makes fun of the Boston detectives.
You take two drinks...
...whenever someone is killed.
...whenever Smecker does something that could be construed as "fabulous".
...whenever someone uses a racial slur.
You finish your drink when...
...they kill the cat.
Nobody has ever made it through this drinking game. One time, Scott left the room to piss and returned to be informed he was back 32 drinks. Do you dare to dance with the Saints?
