Here's something that I wish I had while studying for the SATs: Justin Heimberg's Yo Momma vocabulary builder book, which uses the one-liner joke to teach new words!
Yo momma's so emaciated, she can hula hoop in a fruit loop.
Yo momma's so obtuse, she thinks a webcast is when Spider-Man goes fishing.
Here's an interview with Justin at ABC News: Link
And yes, that's Justin with his mom (who happens to love the book, btw).
