Episode: Season Three: The Telltale Moozadell This one is a tricky find. But it is true. Lady Gaga the Born this Way singer was in The Sopranos. The then 15 year old - billed by her real name Stefani Germanotta - plays a friend of AJs. In this episode the gang of friends vandalise the school swimming pool and trophy cabinet which leads to AJs expulsion from school. AJ is ultimately found out by his pizza being left at the scene of the crime and giving the episode its title: The Telltale Moozadell. Interestingly, Michael Imperioli who plays Christopher Moltissanti on the show wrote the now infamous episode. Germanotta would break through with the smash hit Just Dance 7 years later, followed by the behemoth album The Fame. She is today, of course, one of the biggest pop stars on the planet. Germanotta is barely recognisable here as a 15 year old high school student. One of Gagas most famous fashion statements - a dress made up of slabs of meat worn at the 2010 MTV Video Music Awards would not look out of place at Satriales. http://www.youtube.com/watch?v=QrainCFg9BU Are you surprised by any of these entrants?
