New Pics: 'How I Met Your Mother''s Barney in a Fat Suit

When the gang realizes that Barney (Neil Patrick Harris) and Robin (Cobie Smulders) are miserable together, Ted (Josh Radnor) and Marshall (Jason Segel) request Lily's (Alyson Hannigan) help in breaking them up. Lily devises the perfect plan, calling in help from Robin's famous friend, Alan Thicke, playing himself. "The Rough Patch" episode of "How I Met Your Mother" airs Monday, Nov. 9 at 8 p.m. on CBS. These "fat" photos are from a fantasy in which Barney has been "eating" his feelings, and Robin is losing her hair from stress.
