Mick is out around town doing a bit of shopping, in one particular store he spots something shiny behind the counter and says to the assistant, “What’s that thing there?”
“It’s a thermos flask,” says the assistant.
“What does it do?” Mick asks.
“It keeps hot things hot and cold things cold, sir,” she replies.
Mick buys the thermos flask and takes it to work the next day. At lunch time he sits down and takes it out of his rucksack.
“What’s that thing?” Paddy asks.
“It’s a thermos flask, it keeps hot things hot and cold things cold,” Mick says.
“Is that so? What’ve you got in it?” asks Paddy.
Mick says, “Two cups of coffee and an ice cream.”
