Write a funny story with once happened to your beloved pet (or about your friends pet)

I think anyone with a pet has one, here's one of my favorites.
First, let me set up the situation. I have a very large black cat (7,5 kg or so, not fat, just large). At the time I was living with a roommate, her son and her cat. Her son was a baby, so we had the Schwann's guy drop by so she could buy mixed veggies and other stuff from him.

Well, one night the guy was there. He would sit in a chair and chat while my roommate looked through the catalog and made her selections. My cat strolls up, flops down, rolls onto his back and grabs this guy's shoe - claws out - and proceeds to lick the bottom of the man's shoe vigorously.

We were mortified. The guy was afraid to move and I had to physically remove the claws from his shoes and drag the cat away. I locked him in my room for the rest of the visit.

The Schwann's guy said he must have stepped in something that had spilled.
