Scooby-Doo, Where Are You!
The gang caught Samson and Max the Midget's tandem bike split in half while they were riding, and the accident that followed. After Scooby-Doo saved Max as he fell from a high branch, the latter told the them they had left the circus they were working at because they thought it was jinxed. They then went on with fixing their bike.
Samson returned after the gang solved the mystery (although the same can't be said for Max).
