Museum Buddies Ben Stiller and Robin Williams Pal Around at Baghdad Zoo

Ben Stiller is used to chasing Robin Williams around museums, thanks to their hit comedy A Night at the Museum and its sequel, but on April 3 the duo found themselves clowning around at the zoo! The day before Stiller begins performances in Broadway's The House of Blue Leaves, the actor headed over to the Richard Rodgers Theatre to check out Williams in his debut Broadway show, Bengal Tiger at the Bagdad Zoo. Stiller brought along wife Christine Taylor and mother Anne Meara (who will join off-Broadway's Love, Loss and What I Wore on April 27), where they ran into film director Garry Marshall backstage. Take a look at the Stiller family fun day below!
