A Rabbit walks into a restaurant, goes up to the waiter and says, "I want a cup of coffee.” The waiter says, "We don’t serve coffee here".

So the Rabbit leaves, but when he leaves he sees two friends entering so he joins them. His friends ask for a drink and sandwich but the rabbit says "I wanna cup of coffee"

The waiter says, "We don’t serve coffee here"

So the rabbit leaves again, but he sees two more friends so he joins them. His friends order a drink and a sandwich but the Rabbit still says, "I want a cup of coffee"

"Look,” says the waiter "we don’t serve coffee here. Now leave or I will nail your ears to the table!"

So the rabbit leaves, but he yet again sees two more friends and enters. But this time the rabbit says, "Do you have a hammer?"
"No" replies the bartender.
Do you have any nails?"
"No"

"Then I want a cup of coffee"
