Funny jokeA
biologist was interested in studying how
far bullfrogs can jump. He
brought a bullfrog into his laboratory,
set it down, and commanded, "Jump,
frog, jump!"
The frog jumped
across the room.
The biologist measured the distance, then noted in
his journal, "Frog
with four legs jumped eight feet."
Then
he cut the frog's front legs off. Again he ordered, "Jump, frog,
jump!"
The frog struggled a moment, then jumped a few feet.
After
measuring the distance, the biologist noted in his journal,
"Frog
with two legs jumped three feet."
Next, the biologist cut off the
frog's back legs. Once more, he
shouted, "Jump, frog,
jump!"
The frog just lay there.
"Jump, frog, jump!" the biologist
repeated.
Nothing.
The biologist noted in his journal, "Frog with no legs -
lost its
hearing."
