When engaging in anal sex and you take your thang out of your girl's butt and draw a charicature on her ass with it, this is known as performing a rolf harris.
A fag that ruined two very good songs (Queen - Bohemian Rhapsody and Led Zeppelin - Stairway to Heaven). He decided to put a "Wobble Board" and a digeridoo solo in Stairway to Heaven. Although he did this to Stairway to Heaven, he didn't do much to Bohemian Rhapsody. He did alot of other stupid things like signs his artwork with a caricature of himself as a kangaroo which is named "Rolfaroo". Look up more by searching for him on google.
I don't buy the schmegegge about Morty sleeping with Moira.
His version of the story was pure schmegegge.
The whole schmegegge was made up to get Liz a little bit of attention.
