Two drunkards, Tom and John, are talking about which kind of liquor is the strongest.
Tom said, "I think Whiskey is the strongest liquor in the world."
"No, XO is the strongest," John protested.
Tom suggested, "Let's do an experiment then."
"Ok. No problem," John agreed.
So, they bought two mice, one was white, and the other was black, also, one bottle of Whiskey, and one bottle of XO.
They let the black drink Whiskey, and the white one to drink XO.
After a few second, they found that the white mouse fell to sleep after a few drops of XO, the black one ran away after a few drops of Whiskey.
Tom was happy, and said,"See, XO is stronger."
Just at that time, to their surprise, the black mouse came with a brick in its paw, and the black mouse asked them, "Where is the cat?"
