Jokes for kids are a treat to illustrate. Here are some I did recently for a publication. The challenge is take the riddle/joke and interpret the punch line.
Below: The joke at the top of the illustration isn’t the one that goes along with the drawing. The actual joke is: “What is a fish’s favorite treat?”
The answer: “Gummy worms”. Heh.
Below: And I just wanted to play around with one of the fish above, so isolated him, changed his eyes up and simplified the background. He-llo, fishy!
