Several years ago, when I was at Wadfest, someone's daughter dressed as Tiffany and one of the guys dressed as Rob Anybody. They got the girl to hold out her had and the Feegle to stand at the other end of the field and then, by getting the camera angle just right, it looked like a small Feegle standing on Tiffany's hand. It really looked effective and not a Photoshop in sight.
