Speaking of which, was his girlfriend Trisha?

Yes, but who was the guilty party? Phyllis? Michael? The bridesmaid who left the room at the onset of the scene?

Pete could potentially be Shaggy. He did try marijuana at the close of one episode.

I think part of Peggy's problem is that no matter how successful she is, there are people she works with that still see her as a secretary who caught a lucky break. Don's really one of the only people who appreciates her talent.

I'm pretty sure I saw Zev and Justin from The Amazing Race in small, non-speaking parts in this episode. I think it's really cool that Mike White made this happen.
