Edit: nvm
Take the goat across. Go back and take the lion across, then take the goat back with you, then take the hay across, then go back and take the goat across.
Cid: Correct. OR, you could take the goat first, then the hay, then bring back the goat, then take the lion, and finally bring the goat.
See? Easy but fun. 
how exactly did you end up with a goat, a lion, and a bag of hay? some kind of crappy lotery?
anyway since you did’ent post a riddle I will.
what goes up a chimney down but can’t go down a chimney up?
:moogle: ??? cait that makes no since.
Smoke?
What has a neck, but no head?

An umbrella ?
What has a neck, but no head?
yeah you got it that time.
a tennis racket?
:moogle: a knife?
A bottle.
You have five machines that produce butter and one weighing scale. Now then, one of the machines is malfunctioning and producing one extra ounce per pound of butter. There is no difference that can be seen or felt, but it’s there. Anyway, you can only use the scale once, but you can put any amount of butter on it you want.
How do you figure out which one is malfunctioning?
You take the butter produced by all the machines and weight them all at once; put you them on the scale one at a time so you can see the wight increase incrementally. Whichever one increases the weight by more than a pound is the malfunctioning one.
He said you can only use the scale once.
Yeah. You weigh it all at once. But you keep adding the butter one at a time instead of putting it all on at the same time.
And now a poetic riddle:
With the South, it sits face to face,
And the North, the while, it doth face;
If the figure be sad, it also is sad,
If the figure be glad, it likewise is glad!
Please stop posting new riddles when the previous one has yet to be answered correctly and <i>CONFIRMED</i>. kthxbai 
Cuz, y’know. That justs makes it all messy and we don’t want that 
You put one pound of butter from the first machine on, then two from the second, three from the third, four from the fourth, and five from the fifth. If it’s off by one ounce, it’s from the first machine (Only one piece, one ounce). Two ounces, second machine. Three ounces, three machines, and so on.
And Lex’s is a mirror
With the South, it sits face to face, > Reflection is one face looking at another.
And the North, the while, it doth face; >The actual face (Appearance of the mirror, decor) is on the back.
If the figure be sad, it also is sad, > Reflection
If the figure be glad, it likewise is glad! > Reflection
Wouldn’t you be using the scale five times since you’re weighing five different samples? With my solution you’re still technically using the scale once even though you still weigh five samples.
And your answer to my riddle is correct. Now I just need to wait for Darkness Beckons.
This one is REALLY easy but, it’s all I can think of right now:
What has four legs in the morning,
two legs in the evening,
and three legs at night?
Edit: Errr, I’m confused, was I supposed to post a riddle yet? -_-
That has to be the oldest riddle ever. The human.
No.
Actually, Xelo is correct, you just put them on all at the same time. If it’s one ounce off, machine one and so on.
Doh… =(
