The Simpsons: Charles Nelson Reilly

My least favourite recurring gag on "The Simpsons" is when a character, after making a mistake or getting in a bad situation, tugs at their collar and makes a strangulated "Euuawwww" noise (impossible to spell). From a commentary on the Season 6 DVD, I learn that this is based on Charles Nelson Reilly in the TV version of "The Ghost And Mrs. Muir". Interesting that Reilly's most recent credits include a short film called "Gaydar" and "SpongeBob SquarePants".
