Does it have to be something you actually heard differently, or can it be something you heard out of context and understood differently?
If it can be both, I had a great one happen to me just this morning,
The food service business I work for has employee posters distributed that ask, "would you serve it to your family?" It's about getting all the employees to be part of quality control.
Apparently this morning, while I was upgrading some IT equipment on location, the crew made some test food with product that was a little old.
I came around the corner just in time to hear "no, that's disgusting! Would you serve that to your family?" said mockingly, and I started laughing.
I told them, "I know that question's about the product, but I only heard that part of the conversation and I'm laughing because it sounds like you could be talking about literally anything. Like you could have walked in here and found a mess that [guy #2] made on the floor, and asked him 'would you serve that to your family?!?' " They laughed.
Then guy #2 looked at guy #1 and said, "no, but I would serve that to your family."
