GUY and his GIRLFRIEND listen to MECHANIC recite all the things wrong with their car. The GUY keeps calm but inside: THIS IS GONNA BE EXPENSIVE. I KNOW NOTHING ABOUT CARS. EXHAUST MANIFOLD?

A tense moment as the MECHANIC sizes the GUY up. The MECHANIC throws up his hands, "Ok, you got me. You just need a couple of hoses." His GIRLFRIEND smiles
