Adapting to wild players in home cash game

[Wubbie075]

In my weekly home game ($20 buy-in) there are 2 (me and one other guy) of us who "study" the game. The rest of the players are pretty bad to pretty good, relying mostly on general poker knowledge and common sense. We're all friends.

There are two guys who essentially don't know anything about the game besides the rules and basic structure and make wild plays that would be considered by most to be unconventional and generally "bad". We recently opened up a can of worms explaining pre-flop raising and are now dealing with the reprocussions of people not quite understanding how to apply it.

Typical plays from these guys include, but are not limited to:
Raising 10-15BB pre-flop
Seriously overbetting (3 to 4 times the pot) on the flop
Seriously underbetting the pot on the turn and river.

My question is, how do I adapt to these wildly erratic movies? I tend toward pretty tight play in general, so calling these huge bets without monster hands goes pretty well against my nature.

Please keep in mind when replying, I am NOT complaining about the way these guys play. I usually end up ahead when the game breaks regardless, but I know with a few tweaks to my game I can take serious advantage of their unorthodox poor plays.

What I am looking for are suggestions on how to adapt my play in order to take advantage of the gold mine I see in front of me.

Thanks
