We thought going into this debate we weren't going to get the zingers because the moderator said we're going to mute the microphones, there's not going to be cross-talk, no opportunity for Trump to pull his, you know, yeah, Hillary, you'd be in jail in my country, or yeah, only Rosie O'Donnell, or all those little zingers that fire people up. But Trump was restrained and disciplined, and so he just got the zinger in when it was his turn to speak, and he really landed it.
