It's A Small World 

THE worst ride in Disneyland and Walt Disney World. It ruins many a vacation, including some of mine. The ride is two of the three definitions of gay. Suitable for kids and babies under 8, unsuitable for anyone else.

Kid: I wanna go to It's A Small World!
Teen: Only an asshole would ride It's A Small World.

A rule stating that while riding the Its a Small World ride at any Disney park, your party must participate in a deep, serious, and meaningful conversation that lasts the duration of the ride. During the conversation you must be truthful and you cannot refuse to answer anything.
