My game with the teens

In order to gain teenage workers in the technical and sound boards at church (otherwise known as the audio visual guys) I was to make an announcement to the youth group. Well, I knew that a bunch of teens didn't want to listen to me, so I had to do something interesting.
I called up 5 boys that run the system. I then pulled out $1 and said that I would give it to whomever can tell me what the people standing up on stage had in common. They're all boys? Nope, I am not a boy! All sorts of guesses, everyone has blue eyes, everyone is wearing a shirt, blah blah blah, lol. No one got that we could all run the computer system. Not even the boys I called up.
I wanted to show them that you didn't need to be a certain type of person (computer nerd) to learn it. I told them how these boys now have something wonderful to put on their college apps and resumes. Trying to entice them into a mentorship.
I hope it works!
