The Thermos

A blond 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 keeps hot things hot and cold things cold."
"Wow," said the blond, "that's amazing....I'm going to buy it!"
So she took the thermos and took it to work the next day.
Her boss, who is also blond, 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?"asked the boss,
"Two popsicles and some coffee"
