I'll preface this post with a qualifier: there IS language, etc. in these great photoshop tutorials but if you're not offended by blunt humor and sarcasm and you want to learn to use the heavier tools in photoshop these videos (in two full seasons so far) are worth watching!
I laughed out loud

watching
season one, video two and I was hooked. Actually I laughed out loud watching just about all of them. Even if you don't have photoshop, they're funny-but if you do - watch and learn
The host says 'You're probably using about $75 worth of Photoshop...' and he's right

I learned so much from these tutorials and plan to go back through and try them step by step until I have them all down pat.
