Alright, hear's what I think:
1)If Mario failed, he'd try again or Luigi, Yoshi, or even Toad.
2)If Bowser tried to make "sour love" to Peach, he'd probably crush her in bed. If that didn't happen, the fact that Bowser's balls are bigger then Peach's head would get in the way.
3)Who's Baby Fat?
4) Spam flavored cookies, that's discusting!
