one guy with a tie

When I told my parents that Wangari Maathai had been at Luther College for the Peace Prize Forum, they didn't seem too impressed.

Me: Wangari Maathai was at Luther for the Peace Prize Forum.
Parents: Ok.
Me: Do you know who that is?
Dad: Who?
Me: Wangari Maathai.
Dad: I thought you said "one guy with a tie."
Me: Well, yes, I'm sure there was "one guy with a tie" there. Probably many men with ties.
