Irishman in a Bar

An Irishman walks into the store. Curious about a shiny object, he asks, "What is that?"

The store clerk answers, "It's a thermos."

The Irishman asks, "What does it do?"

"It keeps hot things hot and cold things cold."

He buys one. The next day, he brings it to work with him.

His boss, also Irish, asks, "What is that shiny object?"

"It's a thermos."

"What does it do?"

"It keeps hot things hot and cold things cold."

"What do you have in it?

"Two cups of coffee and a popsicle."
