"the carrot on the end of the stick" meaning?

"it's the carrot on the end of the stick"

What does it mean? I don't understand this phrase. please explain it to me!

Thanks, thanks a lot!

It is something that makes you work really hard. Thing of a rabbit with a stick tied to its back, and the stick has a carrot hanging from it. So the rabbit will be running trying to get the carrot.

Really? I thought it meant an unobtainable goal. Always in sight but always beyond reach.

Makes more sense lol

It means you get the carrot on the stick and shove it right up skippies Arse..!! Until he starts hopping around like a flid Rabbit..
