The Pink Panther

Based on the traditions of tonic-sellers in the Old West, the Pink Panther goes under the alias Dr. Phink and sells Vitamin Pink, but then, under orders from the town's sheriff, has to capture a bank robber who springs into his crime-committing youth after he takes one too many pills, which he manages to do so by tricking the crook into taking a heavy dosage of Anti-Vitamin De-Energizer.
