I don't know Italian, but my Italian grandmother had a bunch that she would translate for me. The only ones that comes to mind is "when you walk with a cripple, you become crippled" and "a fish stinks from the head first."

I have heard of the first and third idioms! 

Any Italian idioms that you sometimes use?

I use them all the time, and they are all really old. No one knows what the hell I'm talking about. Mostly they are ones I heard as a child from my older relatives that stuck with me. Now I can't recall many. Here are a few:

"That guy isn't the sharpest knife in the drawer."

"That guy is a little light in the loafers."

"That guy? The lights are on but nobody's home."

"That guy? The elevator doesn't go to the top floor."
