A bar in Cabo San Lucas called the Giggling Marlin makes the ultimate drink, aptly called:

Skip and Go Naked

1 shot tequila
Splash gin
Splash vodka
Splash rum
1½ shots Amaretto
¼ cup fresh orange juice
½ cup pineapple juice
½ banana
Ice 

Put it in a blender until it's slushy.  If mixed in correct proportions (follow the recipe to the letter) you can't even taste the alcohol -- as dangerous as it is good!

Drink responsibly!
