On last night's LATE NIGHT, the stars of Broadway's OH HELLO, 'Gil Faizon (Nick Kroll) and George St. Geegland (John Mulaney) interview Seth Meyers on their show, 'Too Much Tuna." Later, the actors discuss the great traditions of theater. Watch all the clips from the appearance below!

Nick Kroll and John Mulaney's wildly popular alter egos, Gil Faizon and George St. Geegland, have made their debuts on The Great White Way in their acclaimed masterpiece, Oh, Hello on Broadway. Performances for Oh, Hello on Broadway began on Friday, September 23 at The Lyceum Theatre (149 West 45th Street), where it will run through January 8, 2017. Alex Timbers directs.

Respectively, the duo star as Gil Faizon and George St. Geegland - outrageously opinionated, 70-something, native New Yorkers that Kroll and MULANEY first began performing on the alternative comedy stages in NYC. Honed for over a decade, the fictional duo garnered a cult following and found their way onto a Comedy Central special, viral videos and late night couches everywhere. Oh, Hello on Broadway is Gil and George's "memoir for the stage" - a laugh-a-minute two-man tour-de-force that's part scripted, part spontaneous comedy, and totally unprecedented.
