A blonde girl walks into a store and spots something shiny on a shelf. “What is that shiny thing?” she asks the clerk. The cashier says, “That is a thermos.” “What does it do?” asks the girl. The cashier says, “It keeps hot things hot and cold things cold.” “Oh!” says the girl. That would be helpful for me!

“Give it to me!”The next day, she walks into work with her new thermos and sees her boss. She shows off her new thermos and says, “I just got this yesterday, isn’t it great?!” It’s a thermos, so hot things stay hot and cold things stay cold!” “And what do you have in it?” asks the boss. This is what the girl says: “Some coffee and a popsicle.”
