Frisbee Teacher?

Can anyone out there actually throw a frisbee straight?

I need to be taught.  No matter how hard or soft I throw a frisbee, I cannot get it to go straight.  No matter which hand I throw with, my frisbee has a massive hook to it.

I need someone to come teach me.  I played frisbee golf again today, and it was a little embarassing, especially when I got my frisbee stuck in a tree.

I need your straight frisbee help.
