A blond was shopping in a department store, when she spotted a metal cylinder on one of the display tables. She stared at it for awhile, until a salesman approached.
"Can I help you ma'am?" He asked.
"What is that, sir?" She pointed to her new find.
"That is a thermos." He replied.
"What does it do?" she asked as she fiddled with it.
"It keeps hot things hot, and cold things cold" He replied, as he adjusted his tie.
Satisfied she picked it up, and approached the cashier to pay for it.
A couple days later, as she was walking down the street, she spotted her blond friend approaching her.
"What's that you are carrying, Suzy?" Her friend asked.
"It's a thermos." The blond responded
"What does it do?"
"It keeps hot things hot, and cold things cold." The blond continued walking.
"What do you have in it?" the friend asked incredulously.
"Two cups of coffee, and a popsicle." the blonde replied
