Hey guys I got a riddle for you. I might goof it up a little but u will get the idea.
What has only one voice, walks on 4 feet in the morning, 2 feet in the afternoon, and 3 feet in the night?
Good luck. 
Man oh man.
That is a paraphase of the Riddle of the Sphinx, and as old as.
Oh, welcome to the SDMB, BTW.
A basegry (which doesn’t belong to you anymore) which failed to bring you any sweet pastry when it returned, cause it said hello to Jewel and forgot. 
Seriously, the answer is “man” . Been asked many times.
Ok guys here is another riddle that I just remembered from my childhood.
What can you put in a barrel to make it lighter, that u can plainly see, but is impossible to touch?
The answer is “a hole”.
Welcome to the SDMB, by the way.
Advice: Don’t ask anything to do with words ending with “gry” a or “missing dollar”.

The answer is a donkey. Who in the morning has four legs, and in the afternoon you cut one of them off, and in the evening you glue one back on again.

But that would give you 4, 3, 4. Not an answer to the question.

If you cut one of your legs off, do you still have two legs?

Assuming that they let you keep it.
