i'm glad i don't do anything stupid like that. it would freak me out to have some dude in his tightie whities chasing me down.
And thats just the thing. By the way you handled it, look at the lifetime memories you created for these young men.
I guarantee you that 30 years from now they will still be talking about the night some "old guy" chased them down in his underwear and how the chubby kid was the one that got caught and then spilled the beans on the rest of them.
