Yes, I'm still mad about Izzy and George on Grey's Anatomy. Seriously. Izzy has made me cringe before, especially when she cut Denny's LVAD, but you could almost make sense of that. Sleeping with George and then falling for him when he's married - MAJOR Ewww.

It happens on Gilmore Girls, too, mostly Rory. She slept with a married man, though she loved him, but it was totally out of character for both of them. She's Miss Think-It-Through, and till that episode, he always showed her the utmost respect.

Then she convinced Logan to take a boat for a joyride and ended up getting arrested, which led to her dropping out of Yale. You can understand Lorelei's frustration at her throwing everything away.

Lorelei's not immune, either. She went to Rory's dad Christopher's house but kept it a secret from Luke, and when he found out, he was Not Happy.

What do some of your favorite characters do that make you cringe?
