Here’s a chance to see two cast members from The Big Bang Theory interacting with each other 23 years ago. On what was only the fifth episode of the series, 15-year old Johnny Galecki made a guest appearance on Blossom, accompanying Mayim Bialik to a teenage make-out party. If that wasn’t interesting enough, an unknown 15-year old Tobey Maguire also had a very brief bit part in this episode as one of the teens at the party. You can see him at the 3:29 mark of the following clip, though most of his on-camera appearance consists of the back of his head.
