When Robin shows up with a new boyfriend, Gael (guest star Enrique Iglesias), Ted decides he's ready to move on and hit the town with Barney. While out he meets Amy (guest star Mandy Moore), a tattooed party girl.
Gael: Gael. Ted: I'm sorry, so it's Gayle? Gael: Gael. Barney: ...Kyle? Gael: Gael. Marshall: ...Girl? Robin: It's pronounced Guy-el. Gael: It means joyful. That is why I live my life joyfully, and give to others. Especially those less fortunate than I. Ted: I'm sorry, so it's Gayle?
Barney: It's not possible! You cannot have sex on a windsurfing board! Lily: How do you know? Barney: Glad you asked, Lily. I have crafted a list of all vehicles, land-based, aquatic, and airborne, in which / on which it is possible to have sex. Of these 33, I have had sex in / on 31. Windsurfing board: not on the list. Oh, PS in order to hit 33, all I need is bobsled and the Apollo 11 space capsule. Lily: To get that last one, you'd have to break into the Smithsonian. Barney: This conversation never happened.
