"Intervention" is one of my favourite How I Met Your Mother episodes. It actually makes it in my Top 5 How I Met Your Mother episodes. I just find this whole episode entertaining. I love how the gang became obsessed with interventions. I love how they find their old intervention banner and they reminisce about their interventions. I love the one with Robin reenacting the great Vancouver Canucks in full hockey gear. I love the intervention of Stuart being an alcoholic and Barney comes in and offers him a drink. I love the interventions for Marshall's hats, Lily's fake British accent, Robin's tanning addiction, and Barney's magic trick. And I love how they had an intervention for having to many interventions. I love how Barney pretends to be an old man picking up young women and the gang has an intervention at the end of the episode for him. I give this episode a 10/10.
