Three girls all had boyfriends with the same name, so in order to avoid confusion, they decided to give the boys nicknames.

The first girl said: "I call my man 7-Up."

"Why do you call him that?" asked her friends.

"Because he’s seven inches long and is always up."

The second girl said: "I call my man Mountain Dew."

"Why do you call him that?" said the other two.

"Because he likes to mount me and do me!"

The third girl said: "I call my man Jack Daniels."

The others look at her in bewilderment and say: "Why do you call your man that? Jack Daniels is a hard liquor."

"Exactly."
