Prepare a shooter with 1 part Bailey's Irish Cream, 1 Part Kahlua and 1 part Creme De Menthe. Put this aside for the time being.

Grab a martini glass and line the inside with whipped cream. Leave a little space and then balance the shot in the middle of the whipped cream so it is standing supported. After that's done, cover the rest of the shooter with a thick mountain of whipped cream.

The birthday boy/girl/victim has to get throught the whipped cream and knock back the shooter without using their hands. The girls can only use their hands to hold their hair back.
