"Last Cigarette Ever" is a fun How I Met Your Mother episode. I love how the gang gets addicted to smoking and they all try to quit. First of all, it's no surprise that Robin smokes. I think it was mentioned before this episode that she smokes. It's not realistic how the whole gang smokes, but it doesn't matter as I love how this episode is trying to prove a point. I love how Marshall gives into the peer pressure to smoke at work. I love how Lily can still smell the smoke on him even after he showers. I love how you think she'll get mad at him for smoking, but she just starts smoking too. I love how Ted and Barney feel left out, so they smoke too. I love how Marshall's boss has a heart attack and that's when they all decide to quit smoking. I give this episode a 8.5/10.
