I just re-watched the "Office Closing" episode in season 3 and I love how Meredith goes around trying to figure out who it was she agreed to have sex with on her last day at Dunder-Mifflin. It was great because she started off by going into Micheal's office and told him she was still game if he was.
I don't know why she is would actually have sex with Micheal, but that is the second time she has offered him sex. The first of course being the Christmas episode in season 2 where she walked into his office and just took her top off and stood there.
Meredith is a sex addict.
