You Suck at Photoshop is a series of funny tutorials by Troy Hitch and Matt Bledsoe, two friends (whose stuff can be seen on My Own Damn Channel, under the Big Fat Brain section) that did the first video as a one off, making fun of the angry photoshop guys they seemed to always encounter during their jobs at an ad firm.
An internet phenomenon was born and my dad learned lots of photoshop lessons while laughing the whole time.
But what do you think?
