I coach boys basketball and it's darn near impossible to play shirts and skins.

Webgoji - Okay, take off your shirts.
Kid 1 - No way!
Webgoji - Why?
Kid 2 - There are girls coach!
Webgoji - Dude, that's your mom.
Mom - Don't pretend you weren't running around in your underwear last night!

So I guess it just depends on the kids?
