"Mosbius Designs" is a great How I Met Your Mother episode. I love the beginning of this episode with Barney telling Lily a joke and she just leaves for 4 weeks. But that's because Alsyon Hannigan was having her baby. It was so cute how Ted wanted to create his own business and hires this guy named PJ. I love how Robin has thing for PJ because he has some authority, but once PJ gets fired, Robin shows no interest in him until he gets hired again. I love how Marshall created a fantasy football league at work. My favourite scene is when his carrying all this money in his briefcase and he's all paranoid. I give this episode a 8/10.
