Funny stories

What is your most funny story/accident, that happened during sex, and made you laugh?

Mine is:

When my girlfriend was giving me a blowjob she than put on latex gloves, it made me laugh. But than she slid her finger in my anus and poked my prostate. I came straight in her eyes, nose and mouth. We both laughed.

We were undressing, not paying attention to where our clothes landed. My lover's bra wound up being hung on my erect penis!
