Patton Oswalt, stand-up comedian, writer, actor and voice actor, is the latest Twitter enemy of actor Shia LaBeouf.

LaBeouf has had several run-ins with celebrities on Twitter, including Lena Dunham, after his unorthodox means of apologizing after plagiarizing works of “Ghost World” cartoonist Daniel Clowes.

After allegations of plagiarism, LaBeouf tweeted a slew of apologies when it came to light that the actor took parts of Clowes’ 2007 graphic novella, Justin M. Damiano, and used them in his film.

Following the tweets, the actor then hired skywriters to create a five-mile wide apology across the Los Angeles sky which said, “I am sorry Daniel Clowes.”

In the wake of the apologies and the skywriting debacle, several celebrities took to Twitter to voice their disdain at LaBeouf’s actions, including Seth Rogen and Oswalt.

Dear Shia LaBeouf (@thecampaignbook): If you're gonna be that dumb, delusional AND boring when you speak, just go ahead and plagiarize.
