The producers of ‘Breaking Bad’ better be prepared for Lindsay Lohan to beg for a guest spot, because Bryan Cranston told Howard Stern today that he actually learned how to make high quality meth while preparing for his role.

“We were taught how to make meth (by) DEA chemists who were our consultants on the show. We didn’t cook it, but we were told exactly the process at that high level.”

And it must have sounded suspicious when he said he didn’t cook any, because when pressed he said…

“Maybe. I can’t tell you one way or the other. It’s extremely difficult. There are so many volatile components to it that at any given time, you could literally blow up.”

Oh and hats off to the DEA. They gave lessons on how to make meth. On a film set. In Hollywood. But obviously those aren’t the kinds of people who would ever experiment with drugs, so I’m sure nothing bad could come from it.
