Actually Donald's prenup doesn't say this, that is a joke Carlos Alazraqui made on the 3/9/2016 airing of the Stephanie Miller Show in reaction to John Melendez bringing up a REAL story concerning Trump's claim that his wife Melania (not melanoma) does not poop or fart. Seriously.
The following from a 2003 Howard Stern interview (edited, see full interview video below).
|Trump: Howard let me just ask you. You said something a while ago about Beth that amazed me because it applies to Melania. You said you've never seen her do anything, like, bad, in terms of her own personal. ... You said you've never heard her fart.|
Stern: Not only is that true, she doesn't make doody. She hasn't made doody...
Trump: I can say the exact same thing about Melania. ... I've never seen any of that.
Stern: You're probably expecting a big one this year, though.
Trump: Maybe they save that for after marriage. Beth and Melania, maybe they save it for after marriage. (Donald Trump claims his wife doesn't poop or fart by Stefan Sirucek. 2/24/2016).
This explains Trump's comment about Hillary Clinton taking a bathroom break during the 3rd debate being "too disgusting" to talk about... he thinks women's bodies process waste differently than men's bodies do.
Even though, according to Oddee's Fart Facts "people pass gas about 14 times per day [with] the average person producing about half a liter of farts every single day... and even though many women won't admit it, women do fart just as often as men".
I guess you could say that Donald Trump is a dumbsh*t. In this case he's a dumbsh*t regarding women sh*tting... as well as tooting.
Video1: Donald Trump and Howard Stern discuss the "fact" that neither of their wives poop or fart... as far as they know (Trump sez "I've never seen any of that").
Fast forward to the 7 minute mark for the exchange (19:03). Update, 10/26/2016: Sirius whined to YouTube and had the video removed, although the relevant part can be viewed as attached to a 2/16/2016 BuzzFeed article, Trump Isn't Into Anal, Melania Never Poops, And Other Things He Told Howard Stern. (Note: the video, as presented on BuzzFeed has no embed option. I looked at the html in an attempt to find it, but no luck. So you'll have to follow the link to view it).
Video2: Republican presidential candidate Donald Trump remarked on Democratic presidential contender Hillary Clinton's brief absence from the debate stage on Dec. 19 saying, "Where did she go? I thought she quit".
