Tree diagram

Hi,
Could you help me draw a tree diagram of the following sentences:
1. I know you know what they know about the secret
2. I am aching for my old friend
3. She had tried the suit on
I'd appreciate your help

I can't help you with a tree diagram, but that first sentence looks like a fun one to R-K. http://img801.imageshack.us/img801/6199/know.png

I'll work on that one later.

Have fun!
