What's Your Favorite Holiday Beverage?

This one goes by several different names, but for simplicity's sake, I'm just calling it "Eggnog" (quotation marks required). The best part is, there's no measuring units involved. Quantities determined solely by your level of thirst.

1. In a lowball glass (or 24-ounce stein), pour equal parts Bailey's and Irish Whiskey over ice.
2. Stir.
3. Lather, rinse, repeat.

Tasty.

So, what are you drinking this week?

UPDATE: Gotta add my two favorite seasonal beers to the list.

Samuel Adams Old Fezziwig Ale

Anchor Christmas Ale

Honorable mention goes to Sierra Nevada Celebration Ale.

Damn, as if I wasn't already thirsty as hell.
