If you thought we were about to close out the year without a new comedy special from John Mulaney, think again because Netflix just revealed some very festive news: Mulaney’s new special, titled John Mulaney & the Sack Lunch Bunch, will make its debut on the streaming network on Christmas Eve. The Sack Lunch Bunch is a bit of a departure from the typical Mulaney special. As first revealed earlier this year, the special will take the format of a children’s variety show featuring sketches and musical numbers in an attempt “to recapture the magic of that bygone television era when children sang songs about their feelings with celebrity guests on funky outdoor sets.”
