Perhaps you heard that last night, a plucky little drug dealer named Walter White returned to television for his last eight episodes of the award-hoarding Breaking Bad.

But before he began his life of crime, Walter White was a chemistry teacher, and chemistry is what originally made him such a great meth cook. Breaking Bad has always included a lot of science talk, especially in the early days, and the time has come for someone to see whether it holds up.

And by "someone," I mean "Mythbusters."

This particular crossover episode, which airs Monday night at 10:00 on Discovery, is a patently great idea, in part because both shows, while they're wildly different, have a strong stroke of mischief. That may not be entirely obvious, but when you think about why Breaking Bad is great, never forget that creator Vince Gilligan wrote the funny, offbeat X-Files episode "Small Potatoes," with the shape-shifter. Never. And Mythbusters, of course, features experiments designed to determine the plausibility of urban legends, movie scenes, sayings, and claims about history. It's a good match.

Gilligan appears on the Mythbusters episode, along with Aaron Paul, to comment periodically on the findings of Adam and Jamie on the matter of dissolving a person in acid, and Kari, Grant and Tory on the matter of blowing up a room with a handful of stuff that looks like, but isn't, meth.
