Peach is such a bitch I'd say that Bowser is too good for her. :P I mean, just look at your secret, OP. Bowser would devote his whole life to her, and what does she do? SHE GOES AND BAKES CAKES FOR ANOTHER MAN. Psh. Bowser could so do better than that bitch.

(Why yes, I am still holding a grudge against her for her bitchy actions in Mario Kart + Smash Brothers games, why do you ask.)

Although, as an interesting side note, in one of the games Bowser told Bowser Jr. that his mother was Peach, so.
