A fabliau is a type of story that's really silly and kind of naughty! It's usually set in medieval times and talks about things that might make grown-ups blush. These stories are often short and funny, and they're meant to make people laugh. They often have jokes about love, marriage, food, and tricks. Sometimes the characters in a fabliau are played for fools, but other times they're the ones doing the tricking. Fabliaux were really popular a long time ago, and people still tell them today because they're such a funny and clever way to tell stories!
