And really, who could blame him? There are a lot of reasons you can't help but love Paul Rudd. Of course, this isn't the first time the actors have crossed paths. Mark and Paul were pictured together at the Tony Awards in 2006, and it looks like Mark was a little more low-key about seeing Paul back then.
