They are going to make awesome frat boys one day...

I left the buddies alone in the bath for about five minutes a few nights ago. And heard fits of hysterical laughing, so thought I'd better investigate.

Ace: Mom, we drank each other's pee!
Me: (throwing up a little in my mouth) What?? You're joking, right?
Ben: No, we really did.
Me: Tell me exactly what you did.
Ace: First, we peed in these cups. Then, we traded, and put a little bit in our mouth and then spit it out. Ben did it twice, but I only did it once.
Me: (really trying hard to hold back the dry heaves) Did it taste good?
Ace: No!
Ben: No!
Me: Well let's not do that again. That's really yucky and could make you sick. (more dry heaving) Now get out of the bath and let's brush your teeth. Twice. And then throw away your toothbrushes.
