In 1998, an aspiring stand-up comedian named Sebastian Maniscalco left his hometown of Chicago for Los Angeles. He took a job as a waiter at the Four Seasons hotel in Beverly Hills, hoping he'd rub elbows with comedy big-shots while pouring their coffee. Today, he is one of the biggest shots in comedy, himself.  In Maniscalco's latest special, he takes his act to Las Vegas. Sebastian and Willie Geist got together in New York at one of the comedy clubs where he made his name.
