In season two episode one, Eric and Otis (Asa Butterfield) are having a very deep conversation about... masturbating in the boys' bathroom.
Their hilarious convo was interrupted by someone in that bathroom stall. "I wasn't going to come out," they said... "because what you're talking about is very strange and embarrassing, and I thought it would be awkward."
However, Eric doesn't relish in the embarrassment. Instead, he says: "You should wash your hands, you dirty pig!"
And so, his iconic moment was created!
It's so iconic that it's become a meme.
One fan tweeted: "WE NEED THESE PRINTED OUT, FRAMED AND PUT IN ALL THE BATHROOMS @TwitterUK."
It's become so big that people might actually be more hygienic now! A win-win situation all around.
The show has just been renewed for a third season, so hopefully, we get more one-liners from Eric soon!
