Can you spot which guy above is Red Hot Chili Peppers drummer Chad Smith and which is 'Anchorman' funnyman Will Ferrell?

The physical similarities are uncanny, but they have more in common than just their looks. The Chili Peppers spent a good chunk of their career performing naked except for strategically placed socks covering their privates; Ferrell has been known to strip down and bare all in his movies from time to time, especially in his big-screen breakthrough 'Old School.'

Plus, Ferrell played a percussion instrument in a band too -- at least for a fictional version of classic rockers Blue Oyster Cult in the classic 'More Cowbell' sketch on 'Saturday Night Live.' Even Smith sees the resemblance: He's been spotted sporting an "I Am Not Will Ferrell" T-shirt occasionally.
