1)What is it that you can keep after giving it to someone else?
2)What is round as a dishpan, deep as a tub, and still the oceans couldn't fill it up?
3)Scarcely was the father in this world when the son could be found sitting on the roof.
4)What goes up the chimney down, but can't go down the chimney up?
5)When one does not know what it is, then it is something; but when one knows what it is, then it is nothing.
My mind is a sieve with the holes getting bigger every day.
a hole? a tub with the drain open?
