One day a Sardar jee went into a shop. There he saw something which seemed new to him. He asked the shopkeeper, “Whats this?”. He replied, “Its called thermos”.
“what does it do” was Sardar jee’s next question.
“It keeps cold things cold and hot things hot” was the reply.
Sardar jee was impressed. He bought that thermos.
The next day he went to his office carrying that thermos. One of his collegue asked whats this(pointing towards thermos).

“so have you benefited from this?” His collegues inquired.
“YES”, he replied. “I HAVE PUT TWO CUPS OF COFFEE AND A COLD DRINK IN IT”
