For Laughs
On the heels of our Digital Composite project, I found a series of satirical photoshop tutorials on YouTube. ( short films from MyDamnChannel.com) They may be faster to view on YouTube though.
Caution: These may be a bit raunchy for some, but if you've spent hours trying to master photoshop, they may make you laugh til you cry!
