You can go there for the whole thing, but I could choose from this brief selection:
When Palin claims she said "Thanks but no thanks" to the Bridge to Nowhere: Demand a new drink from your hosts, say "thanks but no thanks," and then when no one's looking, take it anyway, then claim you never wanted it. (Via) (from MIT)
Every time Palin mentions a Moose or says something so stupid you think she might be less intelligent than one: drink a Moosehead beer.
Everytime Biden mentions a foreign leader he has met: sip wine -- every time he mentions a Senator as a friend: drink beer.
Every time Palin fidgets and twists her fingers, switch drinks with the person next to you.
Every time Palin mentions Wasilla drink a shot of Jager and howl at the wolves.
(If you go to the original page, you'll find more ideas, and many embedded links)
But since I'm just too old to drink like that, more likely I'll simply add tequila to my margarita for every answer squeezed in that she missed with Katie Couric last week. She said she'd get back to ya on that, so I'm going to drink when she does.
