Petty Tweeter-In-Chief/President-elect Donald Trump went after the closest thing he has to an equal on Friday, when he mocked former California governor Arnold Schwarzenegger for his low ratings as new host of NBC's The Celebrity Apprentice.

It's worth noting that Trump would likely have tweeted something about the new Apprenticeregardless of ratings, but this time he stumbled upon some precious nuggets of truth.

According to Entertainment Weekly, the Monday season premiere of The Celebrity Apprentice lost nearly half its average viewers (44 percent) compared to 2015.

Ignoring the use of "swamped" and the fact that Trump refers to himself in third person by his initials, the tweet accurately references the ratings -- and was then followed up with the class we've come to expect from him.

Adding an additional weird note to this whole exchange, Trump is still technically a producer on the program.

It wasn't long before Schwarzenegger responded...on Twitter, naturally.
