Seth MacFarlane won't be returning to host the Oscars next year.

The comedian, who took some heat for his off-color jokes at the 2012 show, tweeted, "Traumatized critics exhale: I’m unable to do the Oscars again. Tried to make it work schedule-wise, but I need sleep. However, I highly recommend the job, as Zadan and Meron are two of the most talented producers in the business. My suggestion for host is Joaquin Phoenix."
