OK, it may be off-topic, but I think Bob Barker has the best job in the world, as host of The Price Is Right. It's no wonder he never retired!
I once read a quote from Bob Barker's late wife. She said something like, "We have the ideal marriage. I love Bob Barker and Bob Barker loves Bob Barker."
I imagine the price is right ladies also have something to do with why he never retired.
