You've been laughing at my cat pics... Well, someone's laughing with you.

This is Big Guy or Guy for short. He was a stray cat that would come around and once we started feeding him he became one of the family.

This is a pic a friend of mine took of Guy when the friend was living here in this house with me. He got him right as he yawned so it really looks like he's laughing...

Hmm... Maybe the catnip he got into acts as laughing gas with him.
