An airhead walked into a novelty store. She saw a shiny thermos
and asked the clerk what it was. The clerk said, "It's a thermos. It
keeps cold things cold and hot things hot." The airhead was so
impressed, she bought one. She got home, and could not wait to
show off her new thermos to her co-workers. She walked into work
the next day, and it was not long before one of her peers asked
what that shiny thing was. The airhead said, "It's a thermos. It
keeps cold things cold and hot things hot." Her co-worker asked,
"Well, what do you have in it now?" The airhead proudly announced,
"Two Popsicles and a cup of coffee.".
