Dr. Oz's Taint Trick: Fact or Fiction?

Late in the show, a caller named Keith suggested Howard stem his post-pee dribbling with a method championed by none other than Dr. Oz: after urinating, gently press your finger against your taint to expel any last drops. Howard immediately decided to test the theory, donning a wireless mic and stepping into his bathroom: "Hold on. I'm trying to pee. I'm a little nervous because everyone's listening." After doing a few multiplication tables, Howard got over his nerves and got a good flow going. All was fine until he was done and started pressing on his taint: "Nothing's coming out! Nothing!" Frustrated, Howard thought Keith had been putting him on: "He bet his friends he could make me finger my taint on the air."
