Even the biggest artists get pre-show jitters before going onstage. So, to stave off bad mojo, they often conjure up bizarre backstage rituals, and TRL got a glimpse into these strange customs. Like how Aly and AJ dance around and sing "The Snake Charmer" song before they perform live. Or how Fall Out Boy forms a circle and then high-five each other in a particular order. And that Nelly Furtado sometimes jumps around, barks like a dog and meows like a cat! Hey, so far it's working, so keep it up guys!
