A blonde was shopping 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.
“That’s a Thermos,” the clerk said. “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 do you have there?” he asked.
“Why, that’s a Thermos. It keeps hot things hot and cold things cold,” she replied.
Her boss inquired, “What do you have in it?”
The blond replied, “Two popsicles and some coffee.”
