This thread reminded me of a combined activity for the youth about 6 or 7 years ago. The young women were in charge and the young women and young men were lined up in separate groups. One of the young women leaders would ask a question from a list that they created before the activity to 1 girl and 1 boy at a time for them to answer. They went through several questions and I was just sitting on the side half paying attention while talking to one of the other leaders.

Then I hear the young womens leader as a question "What gets stiff when you beat it?" I immediately look up and I see the teen boy get huge eyes and red faced and I just lost it. I had to leave the gym I was laughing so hard. As I was walking out I hear the girl shout "Eggs, it's Eggs!" It took me a good 10 minutes to be able to go back inside, and even then I would just think of it and start laughing again.
