So...they are showing the eps out of order?

I noticed the same thing! Very confusing. And... Steve and Dr. Jim already started a fire in Onno's house!

I saw Bob Saget on Chelsea Lately a while back and he mentioned the new time slot and/or new night for the show. So maybe they're trying to re-start it?

Yes, this is my assumption as well. We already learned about the strip club in the episode where Steve and Jim set Onno's house on fire with the cigars. I understand Onno travels a lot, but it's as if he just met Steve and Anne in this episode. I believe this episode was meant to air prior to the house sitting episode. Maybe they forgot to air it and just added it in now?

The plot of the latest episode makes me think it was the pilot. I don't think the daughter was even in the episode. That said, it was a very funny episode and should have been aired first as the first episode ABC chose to air wasn't nearly as funny or otherwise appealing.
