Videos of random stuff getting cooked in a microwave.

Toner cartridges, glow sticks, marshmallow Peeps, a bar of soap, and an etch-a sketch, to name a few.

We love our celebrities dead

Recommended by JT

All about dead celebrities – how they lived, how they died, sometimes photos of the latter. Kind of a morbid IMDB, it is actually really fascinating.

Finish that Rubik’s Cube

http://www.roobik.com/

Recommended by Matt Marcek

Shows you how to solve your Rubik's Cube, whatever state it may be in. Asks for the colors on your cube (evidently there are variations I'm not aware of) and the color and location of each square in the cube. From there, it walks you through how to solve it.

Family Guy episodes online

Much like the previously mentioned allsp.com. Instead of South Park, it has all episodes of Family Guy, including the Stewie Movie.

Superman vs a Jedi

http://entertainment.howstuffworks.com/superman-vs.htm

or search 'superman vs jedi'
A ludicrous question is posed, and subsequently taken seriously enough to not only answer, but to expound upon. Who would win in a fight between Superman and a Jedi? The Death Star? Wolverine? Professor X? Gandalf? Harry Potter?

Recommended by Atropos.

A simple question with, for the moment, a simple answer. Has an RSS feed to keep you to up to date on any changes that, hopefully, need not be made.

Lemmings FTW

or search 'DHTML Lemmings'

A throwback to the classic Lemmings game, where you can assign a lemming to dig, build, bash to get through obstacles; or use an umbrella to gently glide to the ground below. Your goal is to save as many lemmings as possible from being squished.
