If the blinds are super-duper loose and super-duper passive, then it is okay to open-limp in LP with hands you'd want to take a flop with but not for two bets, like baby pocket pairs and suited connectors. There's a section in HPFAP devoted to this.

The argument is that even though fewer players in the pot would decrease your equity with hands that prefer multiway action, that's offset by the fact that you'll have position, will know exactly where you stand if they bet, and will often get to see all five cards for free.
