1. Every time Arnold eats something that definitely isn't on his meal plan
2. Arnold Schwarzenegger: changeling
   This was originally supposed to be the Spock rule because the movie keeps trying to convince me he's a Vulcan, but then the climax of the movie hinges on Arnold's ability to sniff Danny Devito out like a bloodhound and I don't recall Spock ever hunting Kirk down on pheramones alone outside of fanfic, so... drink for Vulcan nerve pinches, ubermensch intelligence, super strength, "logic," and also super heightened sense of smell
3. Arnold learns new slang
4. drink every time the uplifting tremellos of the score are the only thing reigning this movie in from falling off Dead Ringers canyon on the left, or generic sad road trip movie chasm on the right. Alternatively, drink when the movie is finally gearing up to be at least a little silly, only the sound track to completely ruin it
5. Pro mode: drink for every "Bro"

House Rules that Apply

1. Birdemic: the Rule
2. Product placement
3. Drink when they drink (and smoke)
   (indoors!)
4. Nudity
5. Name of the movie but don't die
