I was working rec ball last night, and I told my partner about what I consider the ultimate pregame I've actually used:
Red. White. Be good.
The be good covers the sportsmanship requirement
My partner was laughing so hard he almost fell over. Actually, I lied -- I've never used this one, but I told him I did because he spent forever talking about stuff like the "black line all the way around." I just want him to shorten his.
