Humor

I came up with a pretty funny joke on Friday, and I was actually fairly proud of myself.  Vinny and I had been talking about his shoes, and how he has to pull the tongue of his shoes up before he straps the velcro straps.  I pointed out how silly it was that shoes have a tongue and people have tongues too.  Then I asked him,
"Vinny, do you have a tongue?"
"Yes, I have a tongue.  It's in my mouth."
"That's silly!" I said.  "I thought only shoes have tongues!"

This led to some more similarly structured jokes:
"Vinny, do you have any ears?"
"Yes, I have two ears, here and here."
"That's silly!  I thought only corn has ears!"

and punchlines
"I thought only tables have legs!"
"I thought only potatoes have eyes!"
etc.

Others I thought of include:

• Bread has heels
• Roads have shoulders
• Cows have calves
• Macaroni has elbows
• Roses have hips

I'm sure there are more out there.  Anybody?
