two immigrants get off the boat in New York, as they walk down the street the first one says "we gotta be careful in American, these American people aren't like the people in the old country"

The second asks "What do mean?"

The first says "For example, American people eat dogs"

The second one says "you're crazy"

Just then they turn the corner and see a big sign that says "HOT DOG".

The second one says "Sonnafabitch, you're right, I'm gonna be sick"

The first one says "Look at the the people lining up, it must taste pretty good, maybe we should try it?"

The second one says "No, I'll throw up and embarrass myself in front of all those people."

The first one says "Wait here, I'll go get some and bring it back, we can try it here where no ones looking, and if we don't like it we can just throw it away"

He returns with two small bags, he hands one to the second guy who opens it looks in, and then quickly closes it.
Then asks "What part did you get?"
