Ha ha! Poor guy about to get a shock in his balls.

I'd like to be the one to administer it. I'd do it ever so gently, gradually and scare the shit outta him by threatening to go fully on and hold the prod in actual contact with his ball-sac while he yelled for mercy. 
Btw: Note the guy on right with his cock out. Don'tcha just wanna give him a jab with it too?
