I'll do one and see if I get enough groans

===========
There are 2 prawn livining at the bottom of the ocean, Daniel and Christian. They're complaining one day about being the bottom of the food chain, when an old cod fish shows up. He goes to Daniel,
"I will grant you one wish"
Daniel thinks for a moment and says
"I wish to be a shark, the top of the food chain"
Instantly, he is so. Christian, fearing for his life, flees. None of Daniel's friends want to be near him, fearful that the shark nature will take over and he'll eat them. Further, Daniel can make no new friends, as they don't believe that a shark can be nice. Finally, Daniel searches out that old cod fish, and begs to be changed back. The cod fish agrees. In a state of extreme happiness, Daniel races back to the bar that he and Christian frequented. He discovers Christian is not there, and goes up to the bartender,
"Where's Christian?"
"He locked himself up in his home, mourning the loss of his best friend."
"Really? I must go and clear things up for him"
And off Daniel races to Christian's home.
Knock, knock
"Go away"
"Christian, its me"
"You're a shark, go away"
"You don't understand, I've met cod, I'm a prawn again Christian."
