Yes, there really is a Ranch dressing fountain and it can be yours for $100! Apparently there was a popular demand for this fountain that Hidden Valley decided to start selling them. A spokesperson told the Today Show:

"In the past, we’ve had requests from people throwing milestone birthday parties, even brides-to-be, for ranch fountains, and they would present the fountain alongside crudité and their favorite finger foods."

The fountain comes with a year supply of Ranch dressing. You can buy the fountain here for $100.
