This joke was off-limits at Donald Trump's Comedy Central roast

Remember the epic Comedy Central roast of Donald Trump back in 2011? Comics from Lisa Lampanelli to Snoop Dogg (!!) roasted the Orange One to a crisp, dogging him for his hair ("What do you say to a barber to get that type of haircut ... 'I fucked your daughter?'" asked Lampanelli) to his creepy relationship with his daughter ("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," joked Jeff Ross).

According to Aaron Lee, who has written for almost every Comedy Central roast since Pamela Anderson's in 2005, the writers get a list of topics that are and aren't allowed. "Each year, the 'roastee' has certain topics they declare off-limits," Lee writes on List. "It's always interesting to learn what is 'sacred' for a celebrity."

Here's a rundown of what was allowed and not allowed:

Anthony Jeselnik, one of Trump's roasters, also noted the same thing during a conversation with Joan Rivers on In Bed With Joan back in 2013. "Donald Trump's rule was, don't say I have less money than I say I do," Jeselnik said. "Make fun of my kids, do whatever you want, just don't say I don't have that much money."

Well, Seth Meyers is on to you, Donald, and he's roasting you for all you're worth now. Which is probably not that much.
