Working with young fellas

One guy I worked with was trying to start a 75 Vette. He cranked it and cranked it and the air was blue. He got out and slammed the door. I got in and (remember it was a 75) loaded the choke and fired right up. He was pissed and I was laughing my head off. He asked what I did and I just told him I turned the key and fired it up. Made him even madder. Never did tell him what I did.
