When was the last time you fell on your butt?

The other night, with both hands full and standing on uneven terrain (dirty clothes on bedroom floor) I suddenly lost my balance and fell backwards – right onto my ass. I knew immediately I wasn’t injured, and the scene struck me as ridiculously funny – I think I laughed for a full minute straight. It had been a good 10 years since my last butt-accident (slipping in the shower), and I realized they happen so infrequently that others might remember theirs as well. Care to share?
