My freshman year in college, I had a roommate who was bright enough but had a tendency to speak before thinking. One day she walked in on us when my friends and I were having a conversation. "What are you guys doing?" she said as she entered the room. "We were just talking about Jim Henson." "Ohhhhh yeah, Jim Henson. Is he still dead?" Three of us burst out laughing while another roomie replied, "No, he's back from the grave and touring with Elvis this summer." She merely looked confused and left again.

I was busy writing some computer program for one of my classes and my roommate asked me if he could use my coffee maker. I said, "sure." The next thing I hear is, "Hey, where do you put the coffee?" I turn to see that he has filled the filter basket with water and is (unsuccessfully) trying to keep the water in the basket by plugging the hole at the bottom with his finger. He and the floor are both covered with water.
