My husband loves PIE. For his 50th I sent out invitations, in a rhyme.. telling everyone his age and not to bring a gift, but for everyone to bring a notecard with their favorite story about him and a favorite pie. Any kind of pie. Pizza, apple, banana cream, boston creme. I asked them to use their imagination. Ice cream and coffee would be provided. I invited 50 people.

Then I had a t-shirt made with a slice of pie on the front and "Happy 50th Sweetie-Pie".

He didn't catch on to the pie thing until the 4th or 5th person came bearing pie. Then he was ecstatic. My mother filled new tins with a piece of each pie to put away for him to eat in the future. Then we cut the rest of the pies up and served them. Everyone loved it.

It wouldn't have to be pie... it could be a cake party, a cookie party, a movie party...whatever that person really likes. You just have to make your rhyme follow the idea. And people like knowing what to buy. Gifts are hard at that age.
