John Oliver isn’t ready to be face-on-a-billboard famous.

The comedian may be about to launch his own weekly show — but as Oliver explained to Jimmy Fallon on The Tonight Show Tuesday night, he still feels weird about things like posing for magazine covers.

After gracing the front of The Hollywood Reporter, Oliver “had to go to the launch party, and they asked what is it like [to be on the cover]. And I said, ‘It makes me feel nauseous and uncomfortable,'” explained the host of HBO’s upcoming series Last Week Tonight. “I looked up at the man interviewing me and realized that wasn’t the right answer.”

Oliver’s fame also puts him on giant subway ads; he told Fallon that he’s disappointed with the people of New York for not adding the proper graffiti to his show’s poster. Old New York City would never let that kind of white space go to waste.
