It sounds like the easiest $100 you'll ever make: All you have to do is out-sing a bunch of tone-deaf drunks in a karaoke contest. And you've belted out "Don't Stop Believing" so much in the shower that you don't even need the stinkin' teleprompter. Then the warm-ups begin. An older, scraggly guy plops himself down in a chair, grabs the microphone, and pounds out "Wanted: Dead or Alive" with such passion and precision, you'd think Bon Jovi himself showed up. "Another Long Island," you figure, waiting for your name to be called. But next up is a guy whose perfectly pitched "This Love," by Maroon 5, makes your Journey rendition seem like a karaoke career-killer. Welcome to the big time. At every Champps, Thursday is karaoke night, and each week's first-place winners compete in the chain-wide finals for a $1,000 grand prize. Good luck. You'll need it.
