It's like a balloon and something bad happening

People who can’t make comparisons make me sad:
Lowe’s Associate: So, it’s like a big arrow?
Me: No, there’s no bow.
Lowe’s Associate: ¬†Then what is it?
Me: A 6-foot arm actuated dart.
Lowe’s Associate: like a slingshot?
Me: No, there’s no elastic material.
Lowe’s Associate: Oh, so like a lawn dart?
Me: ……….. Yes, a lawn dart that can tear through plywood and kill any land mammal ever to have lived.
Lowe’s Associate: ¬†Okay, I think I threw those when I was on the track team. (Or something like that, by then my ears were turning themselves off in an effort to reduce my blood pressure).
