Paddy had a big gash on his head, so he went to the doctor to have it checked out.
“That’s a big slash cut on your head Paddy. How did that happen?” asked the doctor.
“Well you see, it’s like this”, says Paddy. “Me wife hit me on the head with some tomatoes.”
“Be God, that’s incredible,” says the doctor, “I can’t imagine how any tomatoes would make a cut like that.”
“Sure, they were still in the can,” replied Paddy.
