One day a blonde went into Wal-Mart and saw something she liked.

The blonde asked the clerk what it was. The clerk said it was a thermos.

"What does the thermos do?" she asked.

"It keeps hot things hot and cold things cold," the clerk said.

So she bought one.

She brought it to work one day and the blonde's boss, who also is a blonde, said, "What is that thing?"

"It is a thermos," the first blonde said.

"What does it do?"

"Keeps hot things hot and cold things cold."

"What do you have in it?"

"Coffee and a Popsicle."
