Jane Lynch
It only makes sense that the stern yet goofy gym teacher of Glee would be towering over her co-stars at 6 feet tall. You have to be tall in order to play that type of character, and it made her even funnier in her role.
Unsurprisingly, Lynch played basketball in high school and even heavily considered going into the WNBA. Comedy was calling her name, however, and she broke into the acting scene instead.
