Mystery solved

Where Kieran learned roshambo: "Off the hook", Comcast Housemates.

This was on during Wheel of Fortune tonight (yes, that is still our family life at 7pm). I turned and said, "Kieran, is this the commercial you learned rock, paper, scissors from?" He replied, "Well, yeah" with an unspoken *and/or DUUUH* implied by tone of voice.

I vaguely recall seeing it a few times before but I'm still surprised he picked it up so well from that brief blurb.
