I know more or less every Simpsons episode by heart
NAME SPOILERS
I got 62/63, I didn't know Troy McClure. I though he was Lionell Hutz or Gill and spend the remainder of the time trying various spellings of those names haha
and I thought Rainier Wolfcastle was McBain haha.
I had some trouble spelling some of the names right though, Luann for example. And I had a hard time remembering Homer's mother's name.
Trivia:
-Fat Tony is actually called Marion
-Skinner was called Armin Tamzarian
-Comic Book Guy is called Jeff Albertsen
-Duffman is called Barry
