Grey's Anatomy, Season 2

Meredith:
[voiceover] It's an urban myth that suicide rates spike at the holidays. Turns out they actually go down. Experts think it's because people are less inclined to off themselves when surrounded by family. Ironically that same family togetherness is thought to be the reason that depression rates actually do spike at the holidays. [Izzie turns around and smiles at Meredith and George] Yeah, okay, Izzie doesn't count.
