What is the best?

[Shades of Gray]

Two come to mind, one by the late Jim Valvano to an ACC official:

JV: Can you T me up for what I'm thinking?
Ref: No, Coach you're safe on that.
JV: Good, cause I think you suck.

Ref advised that it was such a good line he let it go.

Second was in a game Oklahoma was playing back when Billy Tubbs was the coach. Refs had a couple of calls that went against Oklahoma and were showering the floor with cups, ice, etc. Tubbs was requested to get on the PA system to ask the fans to stop. He obliged by stating the following: "Don't throw stuff on the floor, NO MATTER HOW BAD THE REFEREES ARE!"

These refs were not as amused and rewarded Billy with a T.
