I'm re-watching the show, and there's an episode in season seven where Eric's with Donna at a take back the night rally. Hi-jinx ensue and it winds up with Eric running with angry feminists in hot pursuit.
"I'm one of you, ladies!" screams Eric as he flees.
Donna yells after him: "Run, Eric! Run like Bruce Jenner!" and then laments that Eric doesn't "know sports".
