Found a site called "Totally Looks Like" and they have some pretty funny look-alike pictures... Here's a few:

Al Roker Ollie Williams

Seth Rogen Jonah Hill

Bob Terwilliger A Palm Tree

Amy Winehouse Keith Richards

Monkey with Glasses George Burns

pao gasol, nba, llama

Its funny because the look-alike doesn't even necessarily have to be human. Check out more here.
