Oh, it was just too funny!
We've often commented on how David Henesy's characters are frequently called David by the other actors even when he's Daniel or Jamison. It happened especially with Daniel, not so much with Jamison. The fact that his real name and primary character's names are both David clearly didn't help matters.
So, today he played both Jamison and David. Recently, they've been scrunching the credits so that they can hardly be read. Today they left them full size, and - not a matter of an actor remembering - but the credits - called him "Daniel"!!!
