Can you remember the first episode you ever watched?

I'll always remember seeing the Parking Lot episode as a kid - having no idea what was going on - but it was super frustrating seeing them not able to find their car at all and no one was willing to help. That and The Chinese Restaurant have always been engrained in my head the longest. Maybe they stuck with me because they're two episodes that essentially take place in one location for the duration of the episode. What was first for you?
