Comedian Joan Rivers has been quite the busy theatergoer lately, and on March 29, the iconic comedienne made time on her schedule for Bengal Tiger at the Baghdad Zoo. Rivers was thrilled to see the play's star, fellow comic Robin Williams, making his Broadway debut in the production. After the performance, Joan, sporting a coat as furry as the show's title character, headed backstage at the Richard Rodgers Theatre to congratulate with Williams. She even tweeted about the experience saying, "I saw Robin Williams on Broadway. Of course he's hysterical, but he's truly an amazing, serious actor." Take a look at their Broadway rendezvous, then plan your own trip to the Baghdad Zoo!
