I can only ever do this with people who I know in real life. Two of my classmates are just real dead ringers. One of them is a George Harrison look alike and the other Neil Peart. I would post some pictures but they might mind... Here's one of an actor:
Kris Myers of Umphrey's McGee
and Max Martini (Mack on CBS's The Unit)
I think Max's face is a little more chiseled.
P.S. There's a good reason Bernhard looks like Gadd. He is Steve Gadd!!
