Stolen from "The Hollywood Sneeze":
Later in season six of "The Sopranos", crossover happens between Highland and North Jersey.
NYC mob boss Johnny Sack of "The Sopranos" finds out he has a long lost relative in Harry Sachz, best known from the classic "Beavis and Butt- head" episode, "Prank Call". Johnny misdials Harry's phone number from jail - then Harry makes a cross-country trip to meet Johnny in "the joint" after getting the phone number with his Caller ID console.
Johnny and Harry then make a jail break when Harry grabs one of the prison guards and sticks the guard's head in a toilet and flushes - and then sticks a phone receiver up the posterior of another guard. Johnny then has plastic surgery and makes a new life and career for himself in Highland as the new manager at "Burger World". Beavis and Butt-head think Johnny is the coolest manager ever after Todd comes to cause trouble and Johnny singlehandedly beats the snot out of him.
Hilarity ensues on "The Sopranos" later this season in the episode, "Sack meets Sachz"...
