Joke

One day Chagmin was doing an experiment on Flea.

First he cuts off 2 legs of the flea and said "Jump" (the flea jumped).
And then he cutts off 2 more legs of the fla and said "Jump" (the flea jumped).
And last he cut off 2 more legs of the flea and said "Jump" (the flea didn't jumped).
and so Chagmin got the result of:

"After cutting off 6 legs of the flea, the flea became deaf.
