A man walks on a street and sees an open manhole

He cries into it: "Fuck you bitch!"

Then echo replies: "Bitch you fuck!"

A bit puzzled, he cries again: "Bitch you fuck!"

And a second later, he hears: "Fuck you bitch!"

Even more puzzled, he cries inside: "Fuck you bitch bitch you fuck!"

The manhole replies: "Fuck off dude, I'm trying to work here"
