In volume 3 of Mr. Safety Pin And The Good News Rascals, the gang meets Question Mark Mark who asked all kinds of questions about everything. They wonder why he ask so many questions, only to find out that there is no such thing as a dumb question. He teaches them that asking questions doesn't make you look dumb, it actually helps you become smarter. It's dumb to pretend you know the answer and continue to live life never knowing the truth when you can ask and learn the answer.
