Parodies, when do they cross the line?

I got ya Bob, it's not just jive talking you know, at first i was afraid, i was livified, kept thinking i could never post without being parodified.

It takes two though right? Just me and you.

I agree! Very annoying... Nice parody Bob, Elvis all over it =D

Parodies cross the line when they go from a well formed comic piece, designed to entertain, to a constructed work made for the composer's own personal gratification.

It's one thing to be clever and witty, another to take acclaim for other people's efforts.
