Sometimes the "wire" is just a tape recorder (does not transmit).
Frankie: Why do you care? You bugged or something?
Wired person: Naw Frankie, I'm not wired. I'm just curious. Come on Frankie! You can trust me. I won't tell nobody.
Frankie: Alright, alright! Me and Big Tony waited for him at his house. Then when he came home, we gave him a blanket party. But Tony got a little rough and accidentally knocked the mofo's brains out, so we had to bury his body off the freeway by the old farm.
Cops: Police! Freeze sucker! Frank Footer, you're under arrest for the murder of a police officer!
Frankie: Mother fucker! You're wearing a wire? You set me up!
Wired person: Sorry Frankie, I had no choice. (To cop) So now that I served up Frankie, the DA will drop all the charges against me right? I'm free right?
Cop: Ha! Not exactly, since some of your charges fall under Federal jurisdiction. You'll still be spending the next 10 to 20 in a Federal Prison.
Wired person: What?!?!
Cop: Hahaha, don't drop the soap. Take them both away!
