There's a new type of broom out, it's sweeping the nation.

Behind the Groan

Popular From Coast to Coast

Something “sweeping the nation” is spreading rapidly and becoming popular everywhere. A broom sweeps as its ordinary cleaning job, so the phrase describes both a nationwide craze and the tool's basic motion. Present the opening like a genuine product announcement, with mild excitement about the new model. Keep the second clause flowing naturally and avoid emphasizing “sweeping.” The joke lands when listeners notice that the promotional phrase was also a literal performance report.
