Flashback to Barney entering the apartment. Ted, Robin, Lily and Marshall are all standing in front of the fireplace, under the "INTERVENTION" banner. He says, "What?" and Robin answers, "The magic tricks." Lily adds, "Specifically those involving fire." Barney rolls his eyes. "Guys, interventions are supposed to help people, not attack every little thing you don't like about them." The gang looks thoroughly chastised. Barney walks toward the window. "I'm sorry, but that really steams me." Oh yeah, he's going there. "That really burns me up." They don't see it coming. "I mean, I am filled with a white-hot rage." He roars, growls and shoots fire out of his hands and across the room -- right onto the banner, which starts to burn over the O. The others scurry away from it and panic when they smell burning hair. Barney realizes the banner is still burning and says, "Oh, shoot." Saget!Ted tells us that's the story of the scorch mark. I think we got that, Saget!Ted. I've noticed your kids haven't been around lately. Have you?

Back to the present -- Ted remembers thinking he saw the intervention banner when he was going through the closet. He walks toward the back of the apartment to find it, and Marshall stammers, "So?" Ted says, "So the banner burned up. Why is there a new one? And there are sealed letters here from all of you that say Ted." Ted realizes they were planning an intervention for him and wants to know what it was for -- the Crocs (shoulda coulda woulda) or the hair product. Marshall stiffens up and has trouble looking Ted in the eye. "Not Stella," he says. Ted realizes his friends are concerned about his impending nuptials, as solemn chords take us to commercial.

We're back! Ted says, "You guys don't think I should marry Stella." Marshall says they do, and that they're all really happy for him. Lily tells Ted the plan to hold an intervention for him was just stupid. Ted says, "Well obviously it wasn't, because we agreed not to have any more stupid interventions at our intervention intervention." Flashback time. The fab five are gathered in the apartment, and Ted says, "We're having too many interventions." Flash forward. Ted unfolds the replacement banner and asks, "So what was your big problem with me and Stella?" Barney bursts in the door yelling, "Yes! Yes! In everyone's face! You all said the future Barney thing wouldn't work! You told me I was crazy! My shrink told me I was crazy! Well, who's the narcissist with severe detachment disorder now, Dr. Grossbard?!" This is delicious.
