Somebody filmed a guy at a call center dialing the phone and asking to speak to Tess. He's reading the name from a piece of paper.
The person on the other end seems to want more information so he says the full name: Tess Ticle. Apparently, they want to hear it again so this time he blurts out Testicle. That's when he realizes he's been pranked. He apologizes and hangs up.
