Just "1982 teen comedy" was enough to get me to Fast Times, and though I was only able to make the Sean Penn/2003 connection, I felt pretty confident about it since I knew he wasn't the only up-and-comer in that movie.
I feel a small connection to it, thanks to this Straight Dope thread
from my original run.
Two days in a row with a lock and a sole get by second place.
edit re Farnsworth: I got him, although I got another "father of television," John Logie Baird, on the tip of my tongue first (not fun to have a Logie on the tip of one's tongue), and had to get him out of my way by reminding myself he was British. (I know both names from Ira Flatow's book They All Laughed...
, which is about strange stories behind some famous inventions. It was thanks to that book that I knew the "What insect was the first computer bug" $1M question on Millionaire.)
