I had the pleasure of building large props for the last two episodes of season 2 of The Chris Gethard Show. The main prop was a custom dumpster made to look beat up and dirty on the outside, but clean and comfortable on the inside. The actor Paul Giamatti had to spend an hour sitting inside while viewers called in to guess what was in the duumpster.
For the final episode I converted the dumpster to look like a makeshift teleporter. The dumpster also had a trap door built in for the host to escape through. In adition I built a wooden cage with metal bars large enough to hold a person.
