Just For Laugh (Thermos Flask)

I find that this story is funny..So I would like to share it here..

Ah Beng goes to a store and sees a shiny object.
Ah Beng : "What is that shiny object ?"
Salesgirl : "That is a thermos flask."
Ah Beng : "What does it do ?"
Salesgirl : "It keeps hot things hot and cold things cold"
Ah Beng : "I'll buy it"

The next day, Ah Beng goes to work with his thermos flask
Boss : "What is that shiny object ?"
Ah Beng : "It's a thermos flask."
Boss : "What does it do ?"
Ah Beng : "It keeps hot things hot and cold things cold"
Boss : "What do you have in it !?"
Ah Beng : "Two cups of coffee and one cup of ice cream"

That is the function of the Thermos Flask...
