What's the funniest thing that's ever happened to you?

There are several actually but the one that makes me crack up so hard is this one incident.

I was running into the kitchen(I had forgotten at the time that the floors were waxed), I had socks on, my foot caught on a bag of mine and i go sliding really fast into a book case, onto a chair and onto my butt, my bottom was very sore and my chest hurt really bad from laughing so hard!
