As a way to show the new champ his appreaction, he manages to hire an intern to leave beautiful cake at her trailer. He knocks on the door, and leaves it on the mat, and walks off. 

That cake was damn near still in pristine condition, even if it's in the heat. 

Then from afar, JB was in a car looking with binoculars from afar. 

Intern: Got the cake to her, what's it made out of?

JB: Im not going to tell you, just watch.

After some time, the two just listen to some cassettes in JB's hoopty, until they see her opening her trailer door. 

JB: watch and learn kid, you'll be shocked.

Suddenly, the champ gets cake filling shot on her face and body.

JB: Oh my favorite trick in the book... exploding cake.

Intern: That seems fucked up.... 

JB: you won't know what's fucked up till this... 

The two come out of the car, and we see them blend in as her PAs cleaning her up with some wet wipes and clearing cake up. After the PAs went off to their task, he decided to do a roll up on the dirt with the intern doing the count.

"It's in my eyes! it's in my nose, oh my god I can't get air in my nose! Get it ouuuuut" Korvayne cried, lamenting what she thought was one of the clowns pulling a trick on her, and even worse, possibly a pin attempt. She was half right. It was a pin. But by John Black not one of the clowns. 

She kicked out furiously.

"Oh come on John! You didn't even bring a ref with you. Just that ugo intern!" 

She shoved bits of cake into the intern's face then stormed off.
