Donald Trump will let you make fun of his hair, his family, his sex life, and his failed businesses. But if you question his wealth, that’s a step too far for the Donald.

Back in 2011, Trump was roasted at an event on Comedy Central, and he submitted a list beforehand of jokes that were allowed and disallowed. Here’s the full list, from E. Alex Jung at Vulture and Aaron Lee at List:

ALLOWED: Jokes about Trump's hair ALLOWED: Jokes about Trump's wife Melania (and his two previous marriages) ALLOWED: Jokes about Trump having sex with models ALLOWED: Jokes about the failure of Trump Steaks, Trump Water, Trump Cologne, and other Trump products ALLOWED: Jokes about Trump's failed casinos ALLOWED: Jokes about how Trump only became successful thanks to his wealthy father ALLOWED: Jokes about Trump's weight ALLOWED: Jokes about Trump being attracted to his daughter Ivanka NOT ALLOWED: Any joke that suggests Trump is not actually as wealthy as he claims to be

So as Jung pointed out, Lisa Lampanelli could tell Trump, “What do you say to a barber to get that type of haircut … ‘I fucked your daughter?’” And Jeff Ross could say, “The Donald and I have a lot in common: We both live in New York, we both play golf, we both fantasize about his daughter.”

But make fun of how much he’s worth? Nope.

Some important context: We actually don’t know how much Trump is worth. He says he’s worth $10 billion, but Forbes has put it at $4.5 billion. Yet we can’t know for sure until Trump releases his tax returns — something he’s repeatedly refused to do.
