Noticed something odd during the Junior-for-Mike wife-swap yesterday:
When Mike became the "main host" --when he would bring them back from a commercial, for example -- it sounded odd, like he was a guest on the show acting like it was his show. Nothing wrong with it, but it made me sit up and take notice. (Part of this might have had to do with the murky levels they had on his mic.)
When Junior did the same thing on the afternoon show, it seemed like it was his show, no big deal.
