NBC anchor Brian Williams returned to Jimmy Fallon’s show this week, and for the third time in as many years, the two engaged in the best possible collaborative skit for a distinguished journalist and a comedic musician: they slow-jammed the news. Brian Williams proffered his authoritative baritone in the smooth track hearkening back to the days of yore — last month — when Washington was embroiled in the fiscal cliff negotiations. If anything can make us forget about that partisan back-and-forth, it’s a slow-jam — and Fallon even gets Williams to drop an a capella line all his own. Just don’t call him “Brilly Willy”.
