"Folding and the flop brings a monster".
This is the fish appeal of Hold 'Em: any two cards can win, and the improvement is dramatic. One second you're holding something nasty like a (J2-o) and the next: BOOM! Full House! Not at all like the incremental improvement of 7-Stud, for example. Yeah, it SUX when it goes: open -> 3! -> call -> call and you fold that (J2-o) and watch (J, J, 2) hit the board while pocket aces or kings takes it down. You still made the right decision not to cold call a three-bet with a total junk hand. It's 1087.89 : 1 against flopping a Full to (J2).
Two pair is still 48.5 : 1 against, and that would be a dangerous top and bottom 2-pair, or even bottom two. You simply can't be playing hands like that and expect to flop a miracle. Miracles don't happen that often, so leave that wishful thinking to the fish. If you would'a flopped the Brazils, oh well, it happens. Any two can win, but any two can't win frequently enough to make you +EV over the long haul, which is what Poker is all about.
