This isn't just a shooter - it's a 21 and Having Fun Birthday Challenge! Can the birthday boy or girl do all four? He or she must drink a new shot each hour until they had all four. Then they pick out a shot for everyone else to try. (SOCIAL!) Recipes are on the back and include: Peppermint Patty, Vanilla-Lemon Drop, Sour Puss and Jager-Schlager.
