Wedding Guest
I have been watching the Muppets take Manhattan for years, and have always scanned the guests to see who was who, and where... never have I noticed this one guest in particular, and it took my three and half year old.
During the end where the guests are singing, my daughter comes running into the kitchen while mommy and I are cooking dinner, and she's yelling at the top of her lungs all excited saying "Daddy, Daddy!! It's Gobo's Uncle Travelling Matt!!"
I had never ever noticed him before, but he's sitting in the first row on the viewer's right.
It makes sense that he would be there, as he's the only Fraggle that ventures into Outer Space.
