One Piece Chapter 42, page 2: Yosaku and Johnny

Luffy shows off his poorly drawn pirate flag. Zoro, Nami, and Usopp react with horror and criticism. Luffy laughs, explaining he put a lot of thought into it. Usopp declares Luffy's drawing skills are beyond terrible and takes over the brush, painting a much better version of the Straw Hat Jolly Roger.
