OK, this might not be the worst, but it is a bad one still the same. This is from YEARS ago.
After a nice evening with my date, we settled in to watch a movie at home. We were cuddled up on the couch together watching the show when my cat decided to jump into the scene.
You see, my couch sat next to the window. And my cat would always jump up on the arm rest of the couch so that I could open the window for her to go out.
So my cat jumped up on the arm of the couch. My date reached over and began to scratch my cat on her back. My cat stretched upward in delight, raising her tail high in the air and stretching out her hind legs (as most cats do when you scratch them on their back, just above their tail).
Well apparently my cat must have been feeling a bit ill that evening. As she stretched up, tail raised in the air, she let out a little kitty fart, promptly proceeded by spraying kitty diarrhea all over the front of my date.
Needless to say that put an abrupt end to the evening.
