When I went in to buy pool passes for the family, the woman in charge of processing was already familiar with me. She said what sounded like $118 and I said "Is that 118 or 180?" Triggered a flashback involving words that sound like "ate".
This was about 25 years ago, on a fishing trip while we were relaxing on a boat.
Friend (puts his hand out to me): I need a mate.
Me: What? What's wrong with me?
Friend: What?
Me: I am your mate, right?
Friend: Yes...what are you talking about?
Me: Why would you need a mate when I am right here?
Friend: What are you talking about?!?
Me: What was it you said to me?
Friend: Uh...when?
Me: Just now, when you said you need a mate. What, am I invisible?
Friend: Oh! No, you moron! I need a (enunciates carefully) BAIT.
I should've figured that out since we were on a freaking boat and he was holding his fishing pole... It's easy to confuse how a certain part of a word is pronounced, like "eighteen" or "eighty", let alone "mate" or "bait". ;)
