Also, try pouring Sambuca in your eye as well.. That gets you smashed. Runs round behind your eyeball and the alcohol enters your blood-stream through the capilaries round there...
Isn't that dead messy? Sambuca's all sticky, and I really don't want to wake up covered in it. I do have a habit of setting fire to Sambuca that's in my mouth, though.
Another good one is putting Black Sambuca into a wine glass, lighting it, then using the suction this creates to stick it to your body before drinking it. Good old party tricks.
