In advance on Stephen Colbert’s first night as host of The Late Show on CBS, his late-night competitors are wishing him luck — sort of — and offering some advice. Many of them–  Trevor Noah, John Oliver, Trevor Noah, Larry Wilmore, Seth Meyers and Bill Maher, but not Jimmy Fallon — appeared in a Vanity Fair video (watch it above). Best moment: Noah, Comedy Central’s yet-to-debut replacement for Jon Stewart on The Daily Show, advises the former Comedy Central late-night star to be careful what he tweets. Of course, that’s a reference to Noah’s own problems — to which Colbert shot back, “Oh I know how to be careful what I tweet: #canceltrevor.”

Meanwhile, Colbert’s lead-out James Corden advised him to make sure his very best material was saved for the last minute of the show.

NBC’s Tonight Show host Fallon had his own Twitter fun with Colbert’s opening night:
