A rabbit walks in to a cake shop.
He walks up to the counter and asks ” Do you have a birthday cake with spinach?”
“No I’m sorry we don’t” says the store clerk.
“Ok” says the rabbit and promptly bounces out of the store.
The rabbit comes back a couple of times and asks the same question and gets the same answer so the store owner decides to make a spinach cake for the rabbit assuming his birthday is around the corner.
The next day the rabbit comes in and asks: “do you have a birthday cake with spinach?”
“Yes we do” replies the store owner.
“That must be a really disgusting birthday cake” says the rabbit and leaves the store.
