Can't Touch That Dial is a medal in Plants vs. Zombies: Battle for Neighborville. It is awarded for destroying two televisions.
Its name is a reference to the phrase, "don't touch that dial," used at the end of a show before a commercial.
Zombies gave "Being Trapped in the Smell Jar" two thumbs fallen off and laying on the ground. That's why zombies are battling for Neighborville's brainz like never before.
The easiest way to earn this medal is to destroy the TV inside Major Sweetie's place. After that, quit to Giddy Park and reenter the Town Center. Destroy the TV once again to unlock the medal.
