The button that makes you feel stupid for pressing it, like it’s laughing at you from the ceiling.

I pressed the ha-ha button and it was like the elevator was mocking me. I was mad.

That button is the worst. It’s like the elevator’s version of a joke.

I pressed it once. Then I pressed it twice. Then I gave up and walked out.
