From Common Errors In English:

Drink Up!

Many common verbs in English change form when their past tense is preceded by an auxiliary ("helping") verb: "I ran, I have run."

The same is true of drink. Don't say "I've drank the beer" unless you want people to think you are drunk.

An even more common error is "I drunk all the milk."

It's "I've drunk the beer" and "I drank all the milk."
