One that I have to do all the time is this:
I know that the defense touched it last, but I forget which colour the teams are. So, I have to recall what half we're in and then a quick look to the near bench and I can then deduce which team gets the ball.
I know it's stupid, but the funny thing is I've been eval'd and I ask the guy eval'ing me and he says that he cannot tell what I'm doing.
