Why are Friends and How I Met Your Mother so similar?
Not too much similarities between the show Family Guy and HIMYM. Family guy is a cartoon show and HIMYM is not. One similarity between the both shows are that they based on the Comedy. http://w.atch.me/B7BCJ4
I've wondered that too, but really, when you get down to it, they're not. The characters aren't the same and the stories in HIMYM are typically more, for a lack of a better word, goofy.
they are both dumb sitcoms
Because one is based on the other to capitalize on its success.
they both are TV comedies that follow the lives of a group of young adult friends who are in and out of relationships
