Image from a SBTB Storyboard!

I heard that the following image was taken from a storyboard for an episode from the 7th season of Saved By The Bell: The New Class.  Apparently the scene called for a transfer student to pull down his pants so that Screech could tongue his anus.  However, the protagonist was to rip a powerful fart in Screech's face before the anus tonguing was to begin!  I bet that greedy fart sniffer, Dustin Diamond, wrote the script for this episode!

Does anyone else have additional information regarding whether this really was from a SBTB storyboard?
