Think Geek always has clever copy and clever April Fool’s jokes. I think part of the reason is that some of their real products are so off the wall that their imaginary products don’t seem unfathomable.

This year’s joke was pretty extensive, featuring a home page almost entirely devoid of real products, and instead filled with jokes. I even got their newsletter in my inbox featuring these same products. And even knowing their tendency to have some fun, I still clicked through — “Spazztroids Caffeinated Cereal? I’ve got to get me some of those!”

Some other winners: Betamax to HD DVD converter, a caffeine patch, a USB pregnancy test, USB sun lamp, USB Foreman Grill, Pii Pii brothers Wii game. Check out their web site while the prank pages up!
