Tonight on How I Met Your Mother, we learn all about the benefits and drawbacks of smoking thanks to ex-smokers Marshall, Lily, Ted and Barney who all succumb to the bad habit once again. We also learn more about Marshall's youth when the show features a flashback scene of a 13-year-old Marshall trying to smoke cigarettes in the woods with his friends.
But as the title "Last Cigarette Ever" connotes, the gang will attempt to quit smoking throughout the episode. Going cold turkey, though, is easier said than done. It's a good thing Marshall's new boss, who doesn't know Marshall's name, jumps in the canvas to offer Marshall a pivotal third cigarette that will possibly change the way Marshall feels about smoking.
Meanwhile, we finally meet Robin's new co-anchor Don Frank, a fairly famous reporter on her ridiculously early morning news program, Come On, New York, Get Up. Though sparks fly immediately between Robin and Don, Robin's high hopes for career advancement are crushed when Don makes it clear that being on her show is a low point for him. Evidently, Don, a veteran of cable news, took a public stance against his program's biased reports, and the only place that will hire him is Robin's show. Now, he resents the fact that no one's watching the early news shows, and he doesn't seem to care how his attitude affects Robin.
