Michael Cera also enjoyed making little prank calls when he was a teenager student with his buddy in Heart Lake Secondary school in Brampton, Ontario. As well as his character George Michael made this innofensive prank call in his usual innocent naughty way in Anne's company in "Burning love" episode of "Arrested Development".

"A prank call, also known as a crank call, hoax call, phone scam or phony phone call, is a form of practical joke committed over the Telephone. As with all practical jokes, prank calls are generally done for humorous effect, though there is a thin line between humor and harassment. Prank phone calls began to gain an America-wide following over a period of many years, as they gradually became a staple of the obscure and amusing cassette tapes traded amongst musicians, sound engineers, and media traders beginning in the late 1970s. Among the most famous and earliest recorded prank calls are the Tube Bar prank calls tapes which centered around Louis "Red" Deutsch, and the Lucius Tate phone calls. Comedian Jerry Lewis was an incorrigible phone prankster, and recordings of his hijinks, dating from the 1960s and possibly earlier, still circulate throughout the country to this day.

Reverse calls, baited/unbaited calls:

Typically, prank calls are known for being outgoing phone calls to the victim; however, a method known as the reverse prank call is performed when the victim is actually the caller. As opposed to the hit-and-miss results of traditional prank calling, this style of prank call usually produces humorous results due to the fact that the caller actually believes what they are calling is real, further validated by the prankster answering the phone in a manner that confirms they've reached the right number.
Some performers such as The Jerky Boys make a name for themselves producing albums of their recorded prank calls.
During the early years of The Simpsons, a popular recurring gag involved Bart making prank calls to Moe's Tavern, inspired by the Tube Bar prank calls. The calls usually followed a set pattern: Bart would ask for a person, Moe would shout loudly for the person Bart asked for, and Moe would catch on only after the bar (usually) erupts in uproarious laughter, also threatening violent revenge upon catching the perpetrator.

Moe never seemed to realize that it was Bart who made the call. Once Bart even told Moe that he made prank calls and Moe still did not catch on: Bart: "Well I make prank phone calls." Moe (in a happy voice one uses when talking to children): "Good for you."
