the character that I didn't know had been retired was Mrs. Krabappel. They retired her when Marcia Wallace died. I was confused about that, I think because the person who voiced Miss Hoover left and one point, was replaced, and then came back, so I remembered one of the teachers voice actor being replaced.
I don't watch it anymore but I don't see Hibbert listed as one of characters who's left.
