A woman is at home when she hears someone knocking at her door. She opens it and sees a strange man standing there.
The man asks, "Excuse me, ma’am, do you have a vacuum?"
Confused, she replies, "Uh… yes, but why?"
Before he can answer, she slams the door shut, thinking it’s just another pushy salesman.
The next day, the same man knocks again. "Ma’am, do you have a vacuum?"
Annoyed, she yells, "Listen, I’m not buying anything!" and slams the door again.
On the third day, she tells her husband about it. Furious, he says, "Next time he shows up, I’ll handle it!"
Sure enough, the man knocks again. The husband flings the door open and barks, "Listen, buddy, we have a vacuum! What do you want?"
The man sighs and says, "Oh, thank goodness! My wife keeps telling me to clean, and I was hoping to borrow one!"
