Yesterday, April 6, was the birthday of two of our favorite Jewish celebrities – Zach Braff and Paul Rudd.

Unbelievably, the seemingly ageless Rudd turned 45. Currently filming “Ant-Man,” the sylphlike star is clearly entering middle age with grace and style. Check out his youthful abandon in this legendary lip-sync-off with Jimmy Fallon:

Maybe he can teach Zach Braff, now 39 and last seen shepherding his film “Wish I Was Here” through Sundance, some lessons about how to weather the transition from boy wonder to comedy leading man. It seems like Braff could use some tips: “Wish I Was Here” is reputedly about “a struggling actor, father and husband who at 35 is still trying to find his identity and a purpose for his life.”

We wish them the best as they step lightly through the decades. Just as long as they both keep their sense of humor … and don’t transition into corny uncle jokes.
