Have you met Marcus 'PSP' Rivers?

He's kind of like Kevin Butler, but he's a lot younger and he's all about the PSP. His name is Marcus, Marcus 'PSP' Rivers (we're not confident that's his Christian name) and he's the face of a new ad campaign that Sony's running to promote the PSP and PSP Go: "Step Your Game Up." We saw a glimpse of the little scamp during Sony's E3 presser, but apparently Marcus will be branching off on his own in the coming months.

A PlayStation blog post details the campaign and points out Marcus' YouTube channel which is full of clips from pieces currently running "on over 19 networks." We've embedded a couple of our favorites after the break, so head on past to make with the yucks.
