I think one of the best things about this episode with Frankie was the fact that it was clearly her moment to shine her, but even still, I have to say this wouldn't be as nearly as funny if it weren't for Bloo and Herriman's crazy antics.
Their "catchy" songs and utterly stupid commercials and attempts to piss Frankie off were classic. Frankie's tantrums were great, especially when she herad that song and she was running around the place and Bloo just said "Name calling, so that's what it's come to eh Frankie?".
that was just great.
