gunmen attacked. days away from a deadline as world powers negotiate iran's nuclear program we ask the country's people whether they want to see a deal. have you ever seen a city buried in snow? coming up, more of the bird's eye view of buffalo, new york and how long it might take to dig out from it all. man (sternly): seriously? where do you think you're going? mr. mucus: to work, with you. it's taco tuesday. man: you're not coming. i took mucinex to help get rid of my mucusy congestion. mr. mucus: oh, right then i'll swing by in like 4 hours... just set aside a few tacos for me. man: forget the tacos! one pill lasts 12 hours. i'm good all day. mr. mucus (to himself): wait! your loss. i was going to wear a sombrero. [announcer:] only mucinex has a bi-layer tablet that starts fast, and keeps working. not 4, not 6, but 12 full hours. start the relief. ditch the misery. let's end this.
