Just don't order a sex on the beach cocktail...

Want to hear the most terrible joke ever? (I made this up by the way)

A man walks into a bar and orders a Sex on the beach cocktail. The bar-tender gives him a drink and he tastes it.

"Ew, yuck!" the man says. "What's in this drink?"
The bartender replies "salty water, sand and cum"
"But i ordered a sex on the beach!" shouted the man.
"And that's exactly what you got... just in a glass" said the bartender.
"Well who's cum is this in my drink?"
"The last man who came... he ordered a screaming orgasm"

Terrible huh?
