What has 3 legs going up hill... and 4 legs coming down?

heres $5.

have you heard this joke??

there was a business man and a woman boarding a plane and they were seated next to eachother. the man had the fixin's: the laptop, the techy phone, the Bluetooth, the palmpilot, everything.

the plane was in the sky when the man said to the woman "lets play a game. i will ask you a question and if you cant answer it, you have to give me $5. then you ask me a question and if i cant answer it i will give you $5000.

the woman agrees.

the man goes first and ask the question. the woman can't answer it and loses $5.

its the womans turn and she asks "what has 3 legs going up hill and 4 legs coming down?"

the man ponders this thought and then gets on his laptop and calls all of his business partners to help him figure this out.

after 20 minutes, he gives up and loses $5000.

then, pleased, the woman gets her money and the man ask "so what was the answer?"

the woman gives him $5.

A canines, with a broken leg....while it is going up it may use purely 3 of its legs.So it is going up the hill with 3 legs...the 1st section is replied. the explanation why the canines is going up the hill is becoz there the vetinery rfile resides on the hilltop and he runs a clininc there, and he in no way comes down.He is going from place to place in a Helicopter which he retains in his shed in the back of the sanatorium.So there is not any element in waiting for the rfile again down!!! So the canines gets to the rfile...the rfile heals the canines..and the canines is allright back....Now he comes down the hill with the 4 legs!!!
