Zoo Chase

Policeman: "One of your elephants has been seen chasing a man on a bicycle."
Zoo Keeper: "Nonsense, none of my elephants knows how to ride a bicycle!"

BAD Bunny Wabbit!

A woman walks into a veterinarian's waiting room dragging a wet rabbit on a leash. The rabbit obviously does not want to be there.
"Sit, Fluffy!" she says. Fluffy glares at her, and sopping wet, jumps up on another customer's lap, getting water all over him.
"I said sit, now there's a good Fluffy," says the woman, slightly embarrassed.
Fluffy, wet already, squats in the middle of the room and urinates. The woman, mortally embarrassed, shouts, - "Darn it, Fluffy, will you be good?!"
Fluffy then starts a fight with a Doberman and pursues it out of the office.  
As the woman leaves to go after it, she turns to the rest of the flabbergasted customers and says:  "Please pardon me... I just washed my hare, and can't do a damn thing with it!"

See Spot

I had a dog once. I spilled spot remover on him, and now he's gone.
