"Duel Citizenship" was the most offensive How I Met Your Mother episode that I've watched. I'm Canadian and I usually find all the Canadian jokes pretty funny, but in this episode it's just offensive. You think this show would be different when it comes to Canadian jokes, and it past episodes they were, but in this episode they were just like every other show that makes fun of Canada. I hated Barney in this episode. He should of being praising Canada instead of calling it lame. I love when he got beat up. He deserved it. I don't want Robin to have duel citizenship. I think her character should be completely Canadian. The reason I give this episode a 4/10 was because of the subplot. I love the subplot because Marshall and Ted bond in this episode, and they get closer than they were before.
