Bryan Cranston Just Owned Someone With A 'Your Mum' Joke

Comic-Con is upon us, and it's revealing a bevy of film teasers, cosplayers and a few funny bits from celebrities.

But Bryan Cranston, aka Walter White, took the cake this year with a rather mean response to a question on the Nerd HQ panel.

A fan from Albuquerque, where Breaking Bad was filmed, asked Heisenberg what he would do for fun while in town for the show.

Cranston replied "I’d go and visit your mother once in a while," and then dropped the mic.
