"Robin 101" is a pretty entertaining How I Met Your Mother episode. I love how Barney is not used to being a couple with Robin. I love how he sneaks out of bed as if it was a one-night stand. I love how Barney starts changing into the perfect boyfriend so Robin suspects he's cheating. I love how it's revealed that all this time Ted is teaching Barney everything he needs to know about Robin. I give this episode a 9/10.
