okay got it.

BILLY?

no, i am not billy as far as i know... i am everyone imaginable. 
Oh, okay. My ex-ex-ex employee Billy had a GIFT for garbling instructions while taking notes. This could occasionally lead to high dollar hilarity and a squashed tiny home. "Take the truck back up" somehow became "go back the truck up" and he put the damn thing through some dude's back fence and a tiny home.
That was the first day of the first time he ever worked for me, and I kept him around ever since, until the treacherous little bastard took a job down the street.
*nods i read the tales of Billy. Your guys relationship remind me a little of Rick and Morty. :3
*devises a plan.
Okay, at some point in the near future, go up to the place he works at, preferably naked. Start calling out his name, with random "where are you"s to add a dramatic effect have some Celine Dion playing loudly in your car when you pull up. Once you have found Billy, grab the handcuffs that you put in your pocket. Latch them on to his wrists and say in a really stern voice, "You're coming with me, we have a job to do."
but the prelude is you go all Jackie Chan mysterious magician on the nearest police officer, and take his handcuffs, preferably not naked... this wouldn't be a good sign to have the plan tragically haulted due to being naked too soon. Your next step is vital.
Grab the said truck, call in the local radio station to play Celene Dion's My Heart Will Go On." Thusly you kindly drive the truck into the said building's front office, now this may require some covert ops.
a prelude to that, ask Nick to run into said building and have him rush people into the back room(s) so you don't accidently hurt anyone, that would be bad.
back to the truck... Once the song comes on, simply start the truck and proceed with elegance to grant the truck front seat access to the said building, it is critical that you provide enough speed and momentum to provide the truck to enter effectively enough to where you can successfully open the door, and wobble on out yelling out Billy where are you? Just besure to check under the car unless some unsuspecting human decided it was a great idea to play chicken with the truck. *nods, this plan is foolproof.
