Chocolate
A man was in an ice cream parlor waiting to buy some ice cream. There was one lady in front of him. She ordered a chocolate cone.

The soda-jerk told her he's sorry but they have run out of chocolate. She said, "OK, then I'll have some chocolate."

He told her, "Lady, I'm out of chocolate."

Once again she said, "OK, I'll just have some chocolate."

Exasperated, he said, "Lady, spell VAN as in vanilla."

She spelled van.

He said, "Good, now spell STRAW as in strawberry."

She spelled straw.

He said, "Good, now spell FUCK as in chocolate."

The lady said, "There is no fuck in chocolate."

He replied, "That's what I'm trying to tell you."
