funny expressions

I agree, when I first heard the expression 'losing one's marbles' I didn't know what it was. It was in the movie Hook and the man indeed lost his marbles, that was the whole joke, but because I didn't knew the expression I didn't laugh and was surprised to see other people laugh. It's funny that you remember those things even after a long time. It has been years since I first saw that movie. I also like the expression: it's raining cats and dogs :), and I laughed pretty hard the first time I heard someone say "toodles, poodles"... lol.
