JimQ, I agree. "I Can Bet" is definitely tongue-in-cheek, but it's also a really good pop song.
Paul's sense of humor shows up here in a few places, but it's very subtle (as opposed to his over the top silliness at times). Is it just me, or does anyone else notice that when he sings the lines "I want someone who can save me/When I come home with a zoo/I need somebody who's a sweet communicator/I can give my alligator to" that he's suppressing a laugh when he gets to "...give my alligator to.." at the very end there?
in years to come/they may discover/what the air we breathe and the life we lead are all about/but it won't be soon enough for me
