Grill them for 10 minutes. Now the first steak is done. Put the second steak back on and grill the other side, and flip over the third steak. Grill for 10 more minutes. All 3 steaks will be grilled in 30 minutes.
First man is a good guy.
Second man is a villain. Third man is a good guy. If the first man was a good guy, then he would have told the truth and said that he was a good guy. If the first man was a villain then he would have lied and said that he was a good guy. Thus, the first man could not have said he was a villain and the second man is lying.
