Who was the funniest character on How I Met Your Mother?

How I Met Your Mother is a popular American sitcom that ran for nine seasons from 2005 to 2014. The show revolves around the story of Ted Mosby, who narrates the story of how he met his children's mother to his children. Along the way, he is accompanied by his best friends Marshall, Lily, Barney, and Robin. All of the characters have their own unique qualities that make them funny, but one character stands out as the funniest.

Barney Stinson, played by Neil Patrick Harris, is undoubtedly the funniest character on How I Met Your Mother. He is known for his catchphrases, womanizing ways, and over-the-top personality. His humor often borders on the inappropriate, but he always manages to make the audience laugh.

Barney's character arc is also one of the most interesting on the show. He starts out as a one-dimensional womanizer, but as the show progresses, we learn more about his past and see him grow as a person. This character development makes him even funnier because we are invested in his story and care about what happens to him.
