Limping at super cally tables.

[MrWizard]

I'm at this table with two guys that call raises with any two cards. I i have been value betting my made hands, over betting my huge hands etc. They have sucked out a couple times on some terrible holdings, and i'm wondering if another way to combat these guys is to limp with more hands... the problem is i don't know which ones to limp with and what not to limp with. Like anytwo suited sounds a little to broad. Can someone give me some guidelines on what to limp with?
