One minute it was Kurt Warner going deep ... the next , it was some porn star!?

Super Bowl fans in Tucson, Ariz. were subjected to 30 seconds of hard core porn -- wang and all -- when somehow, the game feed was suddenly interrupted by a clip from an adult television channel.

Yes, this actually happened.

Comcast -- the cable company in Tucson -- is working on an explanation, but right now it appears the porn break-in only occurred in its standard-definition feed reaching analog TV sets.

Fortunately -- or unfortunately, depending on your taste -- high def viewers were spared the wiener shot.
