"Who are you?"

A letterman from Marshall College wearing glasses was present at Arnie's Diner in 1957 when Mutt Williams sucker punched "Joe College". The act was a catalyst for a fight which pulled in many of the diner's patrons. When the lettermen and the greasers confronted each other, this letterman stood in the second row. Indiana Jones went past him and put his hat onto his head in order to mislead the KGB agents that were following him.
Behind the scenes[]
The letterman wearing glasses was neither credited in Indiana Jones and the Kingdom of the Crystal Skull nor had he lines in the movie.
