A mad man saw his friend crying by a flowing river all alone.
He sat down beside him and inquired why he was crying
The other one answered: “I put a cube of sugar in this river but when I tasted, I felt nothing. It’s not sweet!”
I have put, put, and put, it is still not sweet.
The mad friend blew up with laughter and said: “You, you must be very mad!
Did you shake it???”
Common, shake it and taste it again!
