How I Met Your Mother is kind of like It’s Always Sunny In Philadelphia except instead of crazy people, the characters are just yuppies. The humor has always been more eccentric than the cast, save for Barney Stinson (played by Neil Patrick Harris).

The role of Barney led to career boom for Neil Patrick Harris, not just because the character is so great, but because of the irony of the performance: Soon after signing up for a the role where he played the ultimate womanizer, NPH came out as gay.

Meanwhile, the show's also served as a vehicle for Jason Segel (who plays Marshall Eriksen) before he became a full fledged movie star. Lots of talent here. —IA
