Dum-diddlyum...idiom fun!

...idiom fun!  See if you can figure out what these mean without looking them up online.  And then, if you can, share some you like from your culture.  I'd love to read them!

1.  Enough is as good as a feast.

2.  A change is as good as a rest.

3.  You can't see the wood for the trees.

4.  You're as much use as a wet fart in a thunderstorm. 

5.  Better untaught than ill taught.

6.  That's a horse of a different color.

7.  A penny saved is a penny earned.

8.  He can't cut the mustard.

9.  That was a flash in the pan.

10. We're all going to hell in a handbasket.

Idioms are more than just words, aren't they?  Reminds me of this song, which I love so much...
