My all time favorite is still this one. When a coach says something absolutely ridiculous to you, the reply is, "Coach, I'd respond to that but I left my English-Gibberish dictionary at home." 😀
Another is "Coach, there are only two people in this entire gym who don't care who wins - my partner & me. We only care about one thing - that at the end of regulation time, one team has at least one point more than the other." 😀
And, there's always the old standby, "Sorry coach, we're not allowed to call it both ways. We can only call it one way - the right way." 😀
OK, one more. "Coach, let's trade places. You come out here and call the game and I'll sit on the bench and act like an idiot." 😀
