A family member of mine did this as an engineer for Chrysler. He passed on a copy of his “dictionary” to me and I’ve kept adding to it. I enjoy a good malapropism/egg-corn. He’s not around anymore but the legacy continues.

Update we kept our practice a secret though, it wasn’t nice to point these things out to people.

My grandfather was well known at work for, uh, creative sayings. Malapropisms, misheard cliches, or just wild-ass new phrases. His coworkers took to secretly writing them down over the years, and they read them off during his retirement party to universal delight.

A copy of the list ended with us, the family, and has come up during my grandfather's wake and a few times since then.

Absolutely agree that it might not be nice, but context depending it absolutely can be -- as well as a really touching legacy.

Had a boss was terrible in other ways (he got fired over sexually harassing one of my coworkers) but he would constantly mess up common sayings. The one I remember most is "bumpin the bumper traffic" instead of "bumper to bumper".
