There shouldn't be any issues with this cameo because... why shouldn't a boy band be immortalized in cartoon form?

'N Sync stopped by Springfield in the episode 'New Kids on the Blecch' during Season 12. Bart and his pals get discovered by L.T. Smash and they're formed into a boy band named Party Posse that offers the subliminal message, "Join the Navy."

When MAD magazine threatens to release Party Posse's secret, Smash attempts to destroy MAD's building, much to the dismay of 'N Sync, who tried to stop it in the first place.

But nothing beats the "word" at the end of the clip from Justin Timberlake's cartoon self.
