I did this for a contest running on Snafu-Comics... It was to be a crossover of the comics on the website... So I put in Dave of the original Snafu Comics... The Incompetent Ninja from his comic TIN... Grim Jr. from The Grim Adventures from Down Below... And the kid from the Training Wheels comic...
