Weird Al makes parodies and doesn't get sued, what the heck? And some punk named Jason Derulo rips off an entire Imogen Heap chorus and he doesn't get sued. If this is real I'm gonna be annoyed
Weird Al speaks with each artist he's parodying and gets their permission before releasing the song- also he probably pays out royalties to the original artists.
At any rate, this video is pretty well done, I enjoyed it.
