Tennis Everyone?

I am playing tennis, in what appears to be a doubles match. It's quite fun to knock the ball back and forth although I have no clue if I'm winning or not.

For some reason, the other player on my side decides to come and stand next to me when I'm about to serve the ball. This is somewhat off putting and I keep missing my serve. After a few fluffed serves, he decides to stand in front of me meaning that if I do actually make the serve, the follow through will smash him on the back of the head with the racket.

I become increasingly frustrated about this and end up trying to shove him out the way before taking my serve. It's then I realise that he isn't in fact my playing partner, but one of the opposing players. It seems this is the new rule we are playing too - the opponents are allowed onto your side of the net to put you off your game.

I decide that I can probably still manage with one of them trying to put me off and line up for a serve again. It's then that all the officials, the umpire and the ball-boys/ball-girls decide they want to join in as well and I'm suddenly lost in a mini-mosh pit of tennis folk all bumping and jostling each other as I try to make the serve.
