Lucky's Unlucky Day [Catillac Cats] (1x46)

:

Cousin Lucky comes to visit Riff Raff seeking help. It seems everywhere he goes, disaster follows, and his reputation as a jinx is so widespread, everyone runs when they see him coming. Riff Raff gives Lucky a good luck charm, and it really seems to work! However, Lucky becomes overconfident, discards the charm, and once again it rains only on him wherever he goes.
