When Donna first moved in and first met Eric, she punched him in the stomach for looking at her funny, shown in a flashback in the episode Class Picture.It was at that moment that Eric fell madly in love with Donna.
From 2011 to 2015, he starred as Walden Schmidt on the CBS sitcom Two and a Half Men.
They later became the best of friends and hung out with each other all the time.
Eric's love for Donna continued on and on, but he didn't admit his love for her until That '70s Pilot.
Before he made his debut in the silver screen, he had trouble staying in school and was thrown out more than a few times, and he could hardy even manage to stay in college longer than one year.
Well, I guess all of that was not that important because he was actually hired to the “Partridge” show based on his good looks!
