I received versions of this one from Abie, a gentleman who lives southeast and Geodie, from way out west...

Kimberly, a blonde, was shopping at K-Mart and came across a shiny silver Thermos. She was quite fascinated by it, so she picked it up and took it over to the clerk to ask what it was.

The clerk said, "Why, that's a Thermos. It's insulated, so it keeps hot things hot and cold things cold."

"Wow!" said Kimberly, "That's amazing! I'm going to buy it."

So she bought the Thermos and took it to work the next day. Her boss, who was also blonde, saw it on her desk.

"What's that?" asked the boss.

"Why, that's my Thermos, it keeps hot things hot and cold things cold." said Kimberly

"Wow, that's amazing," said the boss, "what do you have in it?"

With a big smile, Kimberly replied, "Two popsicles and some coffee."
