Workers from the Never Mine wash up before eating lunch at Betty Boop's Tavern, where Betty sings and dances while they dine. After lunch is over, the miners all return to work (and reapply their dirt and grime before entering the mine). An excited Bimbo runs around, singing "I Heard", and calls Betty to come down into the mine. She takes the dumbwaiter down, but its cable snaps and it plunges to the bottom. The crash leaves her unhurt, but clad only in her lingerie (Bimbo obligingly returns her dress). The two discover a team of ghosts playing a game of baseball, with a bomb as the ball. Bimbo and Betty head to the surface in the elevator, unwittingly carrying the bomb with them. They send it back down, and the resultant explosion fills all the railroad cars with coal. The ghosts are also blown into the air, and land in graves opened by a laughing Bimbo.
Betty Boop: "You know he said that she said but he didn't say where she got it!"
Betty Boop "But if she said what he said then I think I'm going to stop it."
Betty Boop: "Yes I heard! It wasn't told to me I only heard!"
