Every time Batman mentions his parents' death, drink!
Every time Batman punches someone, drink!note This one will kill you. If he punches an ally, take two.
Every time he says "I'm Batman" or a criminal says "It's tha Batman!", drink! (This one should work for a few mediums. NOTE: Don't try the former if you're reading Shortpacked!. You'll wind up dead).
Take a shot each time there is a blatant ass shot, take two if it's a guy, take three if it's Nightwing.
For the original Batman series a'la Adam West:
Take a sip anytime "bat" is said, in any context.
Take two every time Chief O'Hara says something sterotypically Scottish/Irish.
Finish the drink anytime Robin says "Holy (blank)!"
Drink half a bottle whenever Batman smiles in any Batman animated show. You'll never wind up drinking more than 2.
This rule was definitely here before the premiere of Batman: The Brave and The Bold.
Drink when Batman is in full outfit but speaks in Bruce Wayne's voice (or vice versa) for plot reasons.
Take a sip every time poison/toxic/knockout gas, or any derivatives therein, is used for anything. Seriously, this happens a lot in Batman The Animated Series.
