The Blonde and the Thermos

A blonde-haired woman walks into a store. Curious about a shiny object she asks, "What is that?"
The store clerk responds, "It's a thermos."
The blonde then asks, "What does it do?"
The clerk says, "It keeps hot things hot and cold things cold." So she buys one.
The next day she brings it to work with her. Her boss, also a blond asks, "What is that shiny object?"
She replies, "It's a thermos."
He asks "what does it do?"
She says, "It keeps hot things hot and cold things cold."
He then asks, "What do you have in there?"
She replies, "Two cups of coffee and a popsicle."
