taxi, and the radio was on and it played "I want your sex" by George Michael. That counted for an awkward 3 minutes or so.
Another time - We were at my in-laws for a wedding, so, all of the brother-in-laws decided to go see a movie "Austin Powers" at the last moment, my father-in-law decided to go with us. Of course, he had to sit right next to me. After the movie, he just said, "Well, that was interesting". If it would have been my mother-in-law, she probably would have tried to make us all leave.
