Same same, but different, again. 23 Sept 13

So I was at volleyball practice tonight for the first time in 3 weeks. After doing some warm ups and running some drills, we were going to scrimmage for the last bit. We had 11 girls at practice, so I stepped in to play. Eric, the head coach, was standing just outside the court and said, "Who wants to go to the net and rock off for the serve?"
My instant thought was, "Can girls even do that?"
Turns out he meant, rock, paper, scissors.
I couldn't stop laughing.
