Season 5: Episode 15 - Rabbit Or Duck

Rabbit Or Duck: Barney holds up a sign with his phone number during the Super Bowl and is besieged with responses from women.  He cannot help himself from taking every call and trying to trump the girl he is with.  It is one week until Valentine’s Day and Ted has decided to let Marshall and Lily arrange a blind date with someone, claiming he will marry them.  Don invites Robin to his house under the guise of a party, however, when she arrives with Ted, they find Don alone and naked in the living room and they uncomfortably leave.  Although content with Robin now eating pizza and watching the “Puppy Bowl”, he has to go meet the “arranged” date; Marshall and Lily use one of Barney’s many discarded girls, as they forgot they were supposed to set him up.  Lily ends Barney’s obsession with nonstop girls calling and looking to trump each one by dropping his phone in a pitcher of beer. In the end, Ted and Robin are together on Valentine’s Day watching the “Puppy Bowl”.  The next day, Don apologizes to Robin for his behavior at work (not being naked last night), and proves it by finally wearing pants, and it’s clear she likes him.
