Flipping through the channels this evening, biding my time until 30 Rock, I come across Grey's Anatomy. Hadn't watched it in a long long time, so I tuned in for a bit.
Then. I. See. Him.
Denny. From what, season 2? The guy who was in several episodes and then DIED.
Izzy is standing there talking to Denny, her dead fiancée, about Alex, with whom she is currently dating. About how to tell Alex that she is seeing Denny, who is dead.
