Have to say @Gilles won this round hands down. The floor is yours.

Ok then. Topic: cats

Harry Potter. McGonnagal can turn into a cat.

Thundercats. Ho!

In Piers Anthony's Xanth series, theres a feild near the center of Xanth that has nothing but cat puns. Including the cat-a-pult, Cat of nine tails, Catastrophe (cat-ass-trophey), etc.

LaserCats!
