It's Grey Goose, and it's not that expensive.
I like the following:
Rye 'n Ginger
Gin 'n Tonic
Rum 'n Coke
Jagerbomb
Snakebite
Goldschlagger (sp?)
White Russian
Red Bull + Vodka
Harder stuff I'll take in shot form.
What's the highest % alcohol you've taken in? The worst I had was some nasty rum a friend brought back from the Dominican Republic, 75 proof. I took a swig not knowing what to expect and my stomach was turning for a good twenty minutes. Never again.
Edit:
Beers: MGD, Brahma, Heineken (I used to hate it, but it's grown on me), Guiness, Rickard's Red, Alexander Keith's
