One-Upsman-Chip

S1 E41: The Rangers prevent Fat Cat from stealing the world's largest pearl by replacing it with a painted bowling ball. Chip and Dale then try to have some fun with a battle of the wits to see who can get the last laugh. Chip, pretending to be Ramma-Lamma-Ding-Dong, convinces Dale he has mystical powers and that he is invisible. Dale decides to flaunt his newly acquired talents by taking a walk in the park. Meanwhile, Fat Cat has discovered the pearl is a fake and sends his gang out to capture a Ranger to use as bait. The hoods come across Dale, and Fat Cat takes him back to the scene of the crime to feed the hungry guard shark.
