How I Met Your Mother: “Rally” (Episode 9.18)

This week’s post-Olympics return of How I Met Your Mother was entitled “Rally,” and it was certainly a rallying point for the show. There are now only six episodes left, and this was a great way to really tighten the reins on the final act of the series.
“Rally” spends the majority of the episode in the current timeline. That is to say, the wedding weekend. Barney in completely hungover, and the gang is in need of his hangover elixir, but the only person who knows how to make it is him. We’re given a great flashback where Barney is tormenting Ted by diving into a long-winded tale about how the Manhattan Project was really a cover to figure out the perfect hangover cure. All of them are all too familiar with the cure, except none of them were told the final, secret ingredient.
This results in the group trying to gather all of the ingredients they know. Robin and Lily are tasked with moving Barney, but he is fast asleep. They continue to try to wake him, but only result in throwing him down the stairs. Meanwhile, Ted and Marshall are seeking out grease, which the inn claims they don’t use. In all fairness, this whole plot wasn’t bad, just not memorable.
