Charlie Rose On-Air Sexual Innuendo Going Viral, Courtesy of John Oliver

Charlie Rose is off the air at CBS, but his sexual banter with his "CBS This Morning" co-hosts is all over the Internet ... thanks to John Oliver's HBO show, 'Last Week Tonight.'

Oliver does a running "awkward sex talk" bit, fully dedicated to what -- at the time -- seemed like Rose's playful, yet sexually charged chit chat with Gayle King and Norah O'Donnell.

In one of the clips, you hear Norah tell a guest to "watch his hands, he knows what he's doing" in reference to Charlie holding a female guest.

Oliver's mocking is similar to that of Seth MacFarlane -- who made news when old clips of his surfaced in which he made fun of Harvey Weinstein and Kevin Spacey after their scandals broke.
