HeyNannyNanny.com [How I Met Your Mother]

In Nannies [S8E3], Lily is desperate to find a new nanny the day before she goes back to work and she and Marshall use nanny service website HeyNannyNanny.com to find and interview prospects for their infant son Marvin. However, those efforts run afoul of Barney’s latest pick-up scheme, hitting on single women nannies in the guise of a rich widower. They later find a solution in the form of Lily’s dad, while Barney gets his just rewards in the form of a beating and a warning to future nannies on the site.

Real Life Use:

At the airdate, HeyNannyNanny.com went to a site created for the domain by the show. Instead of a listing of available nannies in the New York area, the site instead contained a ‘bulletin’ with a warning to prospective nannies not to date Barney Stinson with a head shot, list of aliases and various falsehoods he’s used.
