Long before he was starring in every other box office hit, Joseph Gordon-Levitt was just an enthusiastic kid with a love of trivia ... and long hair.
In the episode above, 16-year-old Gordon-Levitt is sporting his classic "3rd Rock From The Sun" 'do and killing it on a 1997 episode of "Celebrity Jeopardy," where he was pitted against Kirsten Dunst and Benjamin Salisbury, who played the middle Sheffield child on "The Nanny."
When host Alex Trebeck read, "Holden Calfield, the hero of this Salinger novel, hates movies, phones, and his classmate Ernest Morrow," Gordon-Levitt (who went by "Joey" at the time) interrupted with some "ooh ooh's." Then, he responded excitedly, "What is 'Catcher In The Rye?' I'm so excited! That's my favorite book."
Though he was right, Salisbury ended up winning it all in Final Jeopardy. But who's winning these days? Definitely JGL.
