Comedienne and actress Chelsea Handler has given Lisa Kudrow's genealogy show Who Do You Think You Are? a big boost after visiting Germany and uncovering her Jewish grandfather's military background. The This Means War star's segment on the U.S. show has yet to air but Kudrow admits it's a big hit with network executives at TLC. Handler says, "I got to go to Nazi Germany - well it's not really Nazi Germany anymore... - and I researched my grandfather, who was a German soldier and I'm a half-Jew/half-German, so, for me, I thought that would be a good dynamic." Kudrow says, "That was a lot of people's favourite episode at the network... It couldn't have been an easy show to do." Handler adds, "I don't have a problem with people knowing that I'm part-Nazi, because I'm a part-Jew, so I figured it was a perfect combo... It's not like I'm gonna find out some terrible thing... It actually turned out much better that I thought, and I got to see parts of the world I hadn't been to, so that was exciting."
