24. Holly Tyler
As seen on: What I Like About You (WB)
Portrayed by: Amanda Bynes
You're right to scrunch up your face like that because almost nobody knows this show existed, except us, and, yes, Amanda Bynes' character, Holly Tyler, was as cringe-inducing as it gets. To describe her character in short-hand, Holly's whiny voice shouted every line of dialogue (all of which were atrocious), since the scripts were all exclamation points. You can imagine, though we don't recommend it, how painful this experience gets five minutes into any given episode.
