No, VoiceofBruck nailed it - what you do is to start singing "It's a Small World" over and over and over and over, but this isn't really any fun unless you inflict it on your family or coworkers, so make sure you whistle it or hum it aloud. A single afternoon at Disneyland causes permanent brain damage this way. When my sins catch up with me and I'm banished to the nether regions "It's A Small World" will be coming from every speaker on every streetcorner...for eternity. Come to think of it, Disneyland is just like that...
In my youth, I worked doing advertisment for Disneyland. One day, we filmed footage of the "Small World" ride. I rode the ride about fifteen consecutive times.
Jimmy Osmond holds no terror for me; I have seen the worst and survived.
Someday, the doctors say, my peculiar blackout spells should end...
