Surprise guest.

My daughter had a BBQ recently to celebrate her wedding. There were all the usual guests; family, friends, co-workers. We all had a really nice time.
When I was coming back from watching the kids ride the pony I noticed a quiet guest standing by the path that I hadn't seen before.
Here is his picture.







We couldn't decide it if was "Fry Guy" from McDonald's or "Cousin It" from the Addams Family and he never said.

Maybe you can decide.
