Gotta be the butter, my wife is the same way. Actually, 6 of us went to a Kubuki steakhouse, and after we went to one of the couples house to watch transformers. Well, the homeowners went to their room to go to the bathroom, but I used the one out near the living room. Well, I started running the water so I didn't gross anyone out, but it just exploded. I'm talking American Pie style. Anyway, I was hoping that they didn't hear, but then I started to hear aerosol spray out side the door and saw it coming under the door. After that, it was on, everybody, man or woman was running to the bathroom. It was crazy, I didn't know one of the couples well, but after that, we had a bond. 
Many years ago in Milwaukee there was the Crypto-Sporidium (sp?) umm outbreak? Contaminated water from the city. Well, I was at this superbowl party with a gf. Foooking huge house. Game room, indoor lap pool. Guy was loaded. You would think the guy would have all his bathrooms functional. The game was getting done and most everyone was upstairs, suddenly I have the need to take an INTENSE shit. I go downstairs and unload like Dumber and Dumber. Go to flush..NOTHING. there is no bucket near, nothing. All the while the smell is permeating me. I hear people coming down and I am just freaking out. I walk upstairs on the opposite side they are coming down. I say to the gf that we need to go. The next day I told her....she was PISSED. Didnt talk to me for about 3 days. LOL
