Alyson Hannigan & Jason Segel (How I Met Your Mother)
Here’s one for all you smokers out there. Alyson Hannigan reported to Elle that she had at first refused to get intimate with on-screen husband Jason Segel because he always smelled and tasted like cigarette smoke. Not nice. But in a surprise move, Segel decided to completely quit the dirty habit rather than just trying to cover it up! We’re wondering if any real-life husband would do that.
