Eddie Deezen - Eugene Felnic
Deezen played Rydell High's resident geek Euene Felnic in the 1978 movie. He went on to reprise his role as Felnic in the 1982 sequel 'Grease 2.'
Felnic went on to star in 'WarGames' but is likely best known for his voice work in animated series like 'Dexter's Laboratory,' 'Kim Possible' and 'The Polar Express.'
The actor married Linda George in 1984. He is also an avid Beatles fan and began writing a column about the band for the magazine mental_floss in May 2011.
