Overheard -- and had to share

I thought there should be a post where we could share the funny things we've overheard while on the road -- on the plane, in the airport, on site, in restaurants, etc.

I'll kick things off with bits of the conversation two older gentlemen were having in the Dallas airport last week. They were sitting right behind me, so I couldn't help but overhear.

The first comment I heard went something like this:
Guy 1: "How many Jews do you think there are in Salt Lake City?"
Guy 2: "About 20."

They talked a bit more, then I heard:
Guy 2: "Is there actually a lake in Salt Lake City."
Guy 1: "No, there's no lake. It's named after the salt flats."
At this point, I had to chime in: "There's a lake!"
Guy 2: "What's it called?"
Me: "Great Salt Lake."
Guy 1: "Where is it?"
Me: "Outside of Salt Lake City."

They were headed to Park City, then going south to the parks. One of the guys knew about Java Cow in Park City, but he didn't know there was a lake in SLC?!?!?!?

So, what funny things have you overheard?
