Hello. I'm sorry to say that I don't speak any Russian at all, but I've been searching all over the internet for Russian expressions on craziness - roughly equivilent to 'mad as a hatter' or some such - and I haven't had any luck, though I have found some good ones on other subjects (I think my favorite is 'to sleep like a marmot.') Are there any Russian idioms for calling somebody crazy? Anything from 'mad as a march hare' to 'he's just nuts.'
Thank you!
