It’s a long string of Polish jokes and first the crowd is hostile, then it’s game, then it’s just bored. The hack is impervious to their heckling, but they’re drunk, they’re horny, they’re a steeltown mob trying to blow off steam at the weirdo burlesque bar and grill and there’s only so long they can put up with this nonsense.
They’re long past the point where simply yelling GET OFF THE STAGE is going to move the needle, so a group of more or less sober welders huddle together for a bit and send their most tactful bruiser up onto the stage. Which, normally that’s verboten, but desperate times, desperate measures; the bartender makes an overt show of turning away to wash some dishes.
“Hey, listen,” the hod says, one meaty, heatscarred hand on the sweaty shoulder of the comedian. “We’re all in your corner here, but don’t you think you should wrap it up?” The comedian doesn’t blink, just rolls right into his joke about the lesbian with a hard-on. The hod shakes him slightly, then harder, but nothing; he doesn’t even make eye contact. With a shrug, he scoops him up in his arms, or tries to, but the hack is boneless as an eel, slips through his arms without missing a beat. One of the other welders, drunker than most, hurls a bottle. It embeds itself dead center in his forehead. “Hey,” says the comedian, smiling mildly. “You shouldn’t oughta do that.”
It’s at this point that they discover the doors are all locked, and the bartender and the waitresses are all gone, but of course by then it’s too late.
