Funnyman Adam Sandler has been working with ex-‘Friends’ star Jennifer Aniston on ‘Just Go With It’, and says he’s been surprised by how witty she is. “I couldn’t believe how quick and funny Jennifer is,” he says of the actress, who has become a favourite romantic-comedy lead in recent years. “I know she is funny in real life, but it was pretty amazing when we were together how much fun we had and how she added to and ended up beating me in scenes,” he continues. “I’d walk back to the trailer saying, ‘I gotta get some writers to help me.'”
