It was a Christmas part where people had too much to drink. I put the goggles on their heads for the hilarity of seeing the drunken fools' reactions. I didn't tell them what it was. 80% of them put the goggles on, and said, "Holy (insert word)." After everyone left, one dude was messing around with goggles until 4 AM, and he was walking around with them on the entire time. As the owner of the house said, the goggles were a "complete mind fuck." Only one person in the house knew what it was beforehand.
