Ummm....didn\'t the show invite him for this birthday celebration? He looks kinda ungrateful if he says no.
Furthermore, outside of this and Golden Road, I\'m pretty sure the average viewer was never aware (or long forgot) about last year\'s 40th anniversary non-controversy, and aren\'t going to rush to their computers to complain because Bob Frickin Barker popped out of a birthday cake wearing nothing but a sash that says Happy 90th*. I think some of you are reading way too much into this (shocking, I know). You know who you are.
