And I think to myself like  Doesn t my face do that?' So I decide to tweet back at him,  Many people don t know this but Donald Trump s real name is Fuckface Von Clownstick. I wish he would embrace the Von Clownstick heritage,  Stewart said, quipping that  Lincoln used to get into this shit all the time. I swear to you, this is true   the man who very likely, given the FBI s preference, be our next President then tweeted  Amazing how the haters and losers keep voting the name Fuckface von Clownstick like they are so original and no one else is doing it,  Stewart recalled, attempting not to laugh too much.  Then he tweeted  What s funny about the name  Fuckface Von Clownstick? It was not coined by Jon Leibowitz; he stole it from a moron on Twitter.' So I tweet back,  We seem to have hit a F*ckface Von Nervestick,  Stewart continues.
