While I agree that Karl was "awkward" at first, he came a long way by the end of the season. Meg started out hamming it up and she was still playing to the camera at the finale. A little bit of schtick goes a long way. She's over-doing it.
Not sure that, as a mother-to-be, I'd be all that thrilled with Buddha on a pedestal. Fast forward a year later and that baby is going to be walking and bumping into things. Wouldn't a shelf, high up on the way, have been a safer choice (while freeing up some much needed floor space!)
