Ep 19. Zoo or False

Ted, Barney, and Marshall are out on a night of debauchery, and as they attempt to gain entry into a trendy new nightclub, they discover that a bunch of women are leaving the club with a giraffe. This creates intrigue, and they're determined to get to the bottom of it. However, when they finally track down the owner of the giraffe, they find out that the animal has a medical condition, and that the owner is quite eccentric - enough to convince them that his stories about bringing a lion to the zoo and convincing security guards that he was Santa Claus were true. Meanwhile, Robin is trying to get over her break-up with Don and goes out with a group of single women she meets in a bar. After drinking too much, Robin starts to believe that she's one of the girls from the group and starts living a carefree life. Throughout the episode, we're introduced to a series of flashbacks that help provide context for these wild and crazy nights.
