If I'm reviewing purely on technique...
...you get a solid 10. Great voice acting, good animation, and the scenery worked well. But in terms of subject matter, I find your choice isn't really -funny- so much as saddening. I can understand the women who are escorts because they want to be. That's not so much saddening as it is a life choice. But the women who are forced into this lifestyle by circumstance or by others makes this kind of a...well, depressing subject. Especially given the world's economy at the moment.
If it's a satire on how Disney "whores itself out", that makes sense, but if that was the honest case, I'd have left the line about Pluto needing a new kidney out at the very least. It kind of spins things down a really dark avenue, away from funny and more into pity.
