I think the following passage from TV Party's tribute to the late early TV comic Pinky Lee bears repeating (emphasis mine):
In August of 1955, NBC agreed to tone down the gratuitous crudeness of 'The Pinky Lee Show' and 'Howdy Doody' by limiting the destruction of property, bad grammar, squirting seltzer water, throwing things, name-calling and other antisocial behavior that would be forbidden in people's homes but was gleefully exhibited by the network's kid show hosts on a daily basis. "Playing a trombone with a mouth full of watermelon is more messy than funny" was one comment from NBC about the changes.
The next time I have watermelon, I am going to try that. I'll use the large bore horn because it's easier to spit the seeds out.
