Considering their shared failings with the opposite sex and the fact that both of them are major dorks with a side slice of goofiness and while neither is designed to be "the funny guy" in their group, they're both hysterical.
Ross might be more of the "main" character in Friends than Marshall is in How I Met Your Mother, but they share a lot in common. They end up with their childhood sweethearts. They get their family dream. Both are almost rocked by their love leaving to pursue their own things. Both have a "break" from their relationship too... It's all there.
In many ways, Ross and Marshall are the best friends the rest of their groups could have. They're not as flawed as some of the others, they're both kind and have big hearts and they will generally do whatever they can to make sure their friends and family are supported.
But how well can you tell them apart? Can you pick out which one said which of these quotes?
