Half/half
So-so. :) Some of them were funny - a number of them, though just couldn't be heard in the song. I think you tried too hard to get an alternate meaning from some clear lyrics, which just made it sort of... dull.
Others, however, were right on. Also, for the flash itself, it's not terrible or anything, but... you know, it was mostly stick figures and pasted pictures. That can be okay with a funny enough joke set up with them, but this was more repetitive. Maybe a different (more comical) animation each time the lyric comes up, so you don't feel like you've seen the whole thing after the first stanza or two?
