Ted’s (Josh Radnor) increasingly non-present girlfriend isn’t the only one opposed to GNB’s plans to destroy the Arcadian on “How I Met Your Mother.”

The recently defected Marshall (Jason Segel) voices his dissent during the May 2 episode, “The Perfect Cocktail,” causing a (temporary) falling out with Barney (Neil Patrick Harris).

So to bring the two best friends back together, Lily (Alyson Hannigan) and Robin (Cobie Smulders) decide that they’ll first have to get them good and drunk — but apparently most spirits are off-limits with the gang as they tend to cause emotional breakdowns, hallucinations, extreme narcissism or lesbian inclinations in at least one of them.

CBS released the above preview that explains just how difficult it proves finding an appropriate beverage. And you can see which beverage they decide on when “The Perfect Cocktail” airs at 8:00 p.m. ET.
