Explain the following joke?\nQ: Why was the broom late? A: It over swept!
Explanation: Brooms are for sweeping; one reason that people are late is because they over sleep. “Sleep” in the past tense is “slept” (everyday I sleep, yesterday I slept). “Slept” rhymes with swept (swept is sweep in the past tense- everyday I sweep, yesterday I swept). This joke is funny because the expected answer is “It over slept” not its rhyme, “It over swept.”
