Whenever I go to a wedding and they have those disposable cameras on the tables that the guests are encouraged to take pictures with, I take the camera, go to the restroom and take a picture of me squatting next to the toilet. I think this is funny, but I have yet to hear from one of the couples how hilarious they thought it was when they had their pictures developed and saw a picture of me next to a toilet. ("Oh, Allison, that was so funny. I can't believe what a great sense of humor you have. You are amazing.") And I've been doing this for eleven years or so through many, many weddings.
Note: I'm not sure why I thought about this right now. Maybe it's because I just got back from the toilet.
