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.

Idina Menzel became an international star with the animated movie Frozen. But Menzel already was a star in her own right, known for her performances in Rent and Wicked, with the latter earning her a Tony award. That unmistakable voice and a determination to succeed have taken Menzel from the wedding circuit on her native Long Island, to sold-out arenas across the country. Idina and Willie Geist got together for a Sunday Sitdown at one of the spots in New York where it all started for her.
