Gosh, there are so many! Just off the top of my head:

* Mary Poppins
* Maria from the Sound of Music
* Fran Fine (The Nanny)
* Mister Belvedere
* Jeffrey (The Fresh Prince)
* Nanny McPhee (the ugly one who casts spells or something)

EDIT TO ADD:

* Alice from the Brady Bunch
* Tony Danza' character from Who's the Boss
* Charles from Charles in Charge

If I had to choose one person to watch Charlie, I think I would choose Maria from the Sound of Music. Charlie would love Maria's singing! Plus he would get a kick out of hanging out on the Swiss Alps. The only problem is that I wouldn't want to marry my governess, so she'd have to be OK with that.

Did we miss any famous nannies or butlers from TV or the movies? Also, if you could have one of these guys help out at your house for one year, who would it be?
