when was the last time you really laugh out hard your stomach aches?

I had a good laugh at the gym the other day. My friend was trying to coach me into spending more time on the elliptical trainer. She kept saying "come on, you can do it for 5 more minutes...if you do I will cluck like a chicken right here in front of everyone..." Finally after I was about 15 minutes past my goal, I told her I was not spending one more minute on that machine unless she agreed to have my name tattooed on her butt! We both were laughing so hard we were crying.
