Tony Tony Chopper becomes a recurrent advertising symbol for a restaurant chain, like those creepy Spong Monkeys in the Quizno's Sub commercials a few years back.
I can immediately see him yelling "I must cure food poisoning" after each take.
Franky tries unsuccessfully to appear as Mister Insides on an educational TV show, but gets sacked for being too unrealistic, and scaring the children by removing parts while on air. On the same series, Hatchi makes a long and successful run as Captain Squidie.
We all know Usopp will appear on C-Span as an analyst. He speaks liar so fluently.
