​"Ho-ly cow! This looks so real! Gave it as a hostess gift. When I walked in, I set it on a white couch. People were horrified that someone could be so careless until they realized it was a joke. Then they ran around trying to fill anyone who hadn't seen it yet. Great fun! It arrives very well wrapped. A little pricey for a gag but well worth it," writes one rave reviewer.

"The package just now arrived, and unfortunately, the cup had spilled and left a mess inside the cardboard box. This is perfect! I'm going to have fun with this," added another jokester.
