Actor and author Jim Carrey self-published his kid’s book this week, and posted a photograph in character for Dumb & Dumber To to promote the book.

In the photo, Carrey reads How Roland Rolls upside down with Jeff Daniels–both of them dressed as characters from the hit 1994 comedy, Dumb & Dumber.

Earlier this year, Carrey spoke about his decision to self-publish “I’m going to self-publish, because that’s just the world right now and I think it’s cool.” (Via Gawker)
