Don't mind the laughing
A blonde was shopping at a Target Store and came across a silver thermos. She was quite fascinated by it, so she picked it up and brought it over to the clerk to ask what it was. The clerk said, "Why, that's a thermos. it keeps some things hot and some things cold."
"Wow", said the blonde, "that's amazing. I'm going to buy it!"
So she bought the thermos and took it to work the next day. Her boss saw it on her desk. "What's that," he asked?
"Why, that's a thermos. It keeps hot things hot and cold things cold," she replied.
"What do you have in it?" he asked?
"Three cups of coffee and a popsicle."
