Apatow was first.
True, the producers of "The Office" discovered the skills of the actor and stand-up comedian first, but it was Apatow who brought him up to the big screen for his bit part as a tortured nightclub door man in "Knocked Up."

Robinson, clearly knowing a good thing when he sees it, hasn't yet expressed a preference between the two.
