In what is sure to be one of the most baffling lawsuits of 2013, Donald Trump is suing Bill Maher for $5 million in charity donations after "proving" his biological father is not, as Maher joked on "The Tonight Show," an orange-haired Orangutan.On this week's episode of "Real Time," Maher responded to the lawsuit by dismissing the entire thing, and reminding Trump that this is a free country where celebrities are made fun of and jokes on late night talk shows are not legally binding agreements."This is known as 'parody,' and it's a form of something we in the comedy business call a joke," Maher said.
