A pair of Polish brothers move to the U.S. and are living in New York City.

They want to fit into American society so they watch the inhabitants very
closely and try to do things other New Yorkers do.

One day they're
wandering around mid-town Manhattan around lunchtime, and they spot a hot
dog vendor.

Brother 1 turns to brother 2 and says, "They eat dogs in
America? Do you think we should try some?"

Brother 2 replies, "Well, we want to be like other Americans, I think we
should try it". So they each order a hot dog, then go sit on the curb to
eat.

Brother 1 unwraps his, looks at , makes a face, and turns to his brother
and says, "What part did you get?"
