One of the best levels was the one where you could all be tanks, and then the trick would be to stay on the start line and wait for your opponents to pull slightly ahead before blowing them up.
Another great one was to choose the level where you are all ice-cream trucks, and holding down the horn to play Greensleeves on repeat to thoroughly annoy everyone.
Bumping into the whoopie cushion to make fart noises.
That bit on the school level where there was a really long ruler, and you could push someone off if they happened to be next to you.
Memories, memories!
