Stephen Colbert apparently thinks that his Time cover photo is just about the un-funniest image in the world — but he’s managing to get a lot of laughs out of it anyway.

The incoming “Late Show” host, who takes over the CBS program Sept. 8, has spent a good chunk of the past 24 hours mocking his own image.

The bulk of Colbert’s gibes seem to revolve around the fact that the ultra-serious expression on his face doesn’t adequately convey his well-documented sense of humor.

“Hilarious!” the first post bearing the Time image read, along with the hashtag ” #ISwearItsAComedyShow.”

Later he added, “You can’t see it from my @Time cover photo, but I’m laughing from the neck down.”

A bit of self-deprecation followed, with Colbert tweeting, “I think the full name of the magazine is ‘The Ravages Of Time.'”

Another image featured the cover with the eyes and nose torn out, with someone — presumably Colbert — wearing it.

“Halloween Idea: @Time Scary Drifter Mask,” the caption read.

Colbert also offered a math lesson on the cover, coughing up the equation, “Comedy plus @Time equals Tragedy.”

He also tossed in a bit of oversharing with the revelation, “Full disclosure: in the rest of this @Time cover photo I’m doing naked tai-chi.”
