[Sir Folds A Lot]

I don't agree with those who are saying that the op should appreciate the donkness of these players. It'll mess up your game playing with these donks who will crack your aces one too many times with crap crap OS. You'll start pushing with mid pair, and it will transfer over to the "real" games.
Just tell 'em it's your house and house rules. If that isn't enough, tell 'em you want to play the right way. Print a few copies of Robert's Rules and give 'em to people to take home and read. As they, your group, play more and see more on TV, they will step their levels up. You may hear some gripes in the beginning, but later will appreciate the consistencies of following the rules.
