Springfield Mystery Spot
The Springfield Mystery Spot was first mentioned in Old Money when it was one of the places that Homer said they could take Grandpa to. Lisa exclaimed that it was just a big mud puddle. However, it appears in Homer at the Bat, when Ozzie Smith disappears forever into it. Past visitors there have claimed to see the face of God, to speak in colors, shed their corporeal bodies and become floating spirits, and take pictures that don't have that annoying red-eye effect. It is basically a shack in the middle of nowhere, over what scientists believe is a nexus between the space-time continuum of several dimensions intersecting in a horrible vortex of chaos. Others say it's just the effects of the shack's wicked paint fumes. Nonetheless, it is an undefinable, unthinkable tourist stop for those who aren't afraid of the unknown or don't mind getting milked out of $10. The mystery spot's motto is "Where logic takes a holiday and all laws of nature are meaningless." The mystery spot successfully nauseates over 650 paying customers per year.
