I'll throw another one out there for ships and giggles.
I was with my church youth group up in Detroid, MI for a convention or something of the sort.
We were coming out of an icecream shop where we had a really nice talk with the employees, to see this guy set up with a karaoke machine and his keyboard. He was playing and saying worship is for losers and things of the sort, and "Jesus Freaks" aren't needed.
So, as everyone was just staring, my friend and I ran across the street, picked up the mic, and started screaming "FREAKS FOR JESUS, FREAKS FOR JESUS!"
The awkward thing about it all?
The machine wasn't hooked up to anything, but our voices managed to fill the entire street.
Oh well, it was fun.
