Betty White is one of the funniest people to ever inhabit the Earth. In the newest addition to her comedy resume, 'Off Their Rockers,' she has devised a hidden camera show that showcases the elderly pranking the public and she sends one of her actresses in to give an unsuspecting man a shock. This clip is one for the metalheads!

While cruising along on a motorized wheelchair, the elderly woman chosen for the prank stops in front of a man sitting on a bench as her phone rings. The ringtone, however, is death metal! She waits and looks around a bit as if she's unaware if her phone is ringing or someone else's. After a moment she picks up the phone and answers in a sweet, endearing voice as she mobilizes once again, leaving the man confused and laughing.
