Susan had not yet seen his 50 in his hair so while he was signing his star she shouted out, "Oh my gosh, Babe! Your hair!"
No, he is not spitting on the cake to blow them all out.
(At least I don't think he did)
This is at the end of the party. Yes, Susan is dressed as Marilyn Monroe and those are Oscars. You can't see it in this picture, they are standing on the red carpet too.
Many of the guests who RSVP'd ahead of time received mini oscars for winning "their category". Yohn won for the best portrayal of Santa Claus. He was up against Tim Allen (from the Santa Clause series), Edmund Gwenn (from Miracle on 34th Street), and well, I can't remember the third one now, but I would vote for Yohn any day cuz' I think he puts in just as good a performance.
Enjoy being 50 Gene and may there be many, many more!
