A lawyer and a senior citizen are sitting next to each other on a long flight. The lawyer is thinking that seniors are so dumb that he could get one over on them easy. So the lawyer asks if the senior would like to play a fun game. The senior is tired and just wants to take a nap, so he politely declines and tries to catch a few winks.

This is an old and outdated riddle but the official answer is: Man... young going up.. old with a cane coming down.

This doesn't make sense,most people answered a young man going up the hill,and then a old man with a cane coming down the hill! Hence the third leg,but a cane is not a leg,it's a walking stick used to support ones inability to walk on two legs.

There are many answers, but I would say a plane when it lands.

What goes up with 2 legs and comes back down with 3?
