Donald Trump says he's suing Bill Maher for $5 million after Trump accepted his offer, making a valid contract.

The "offer," made last month, was to "pay $5 million to Trump’s charity of choice if he provided a birth certificate proving that he’s not 'spawn of his mother having sex with orangutan.'"

Maher was comically commenting on Trump's offer to pay $5 million to Obama's charity of choice if Obama releases his college records.

This lawsuit news is, of course, Trump, once again, hogging — orangutanning — the media spotlight. Fine. I don't care. But to actually file a lawsuit is: 1. An offense against free speech, and 2. An irresponsible appropriation of the public wealth that will be consumed processing the lawsuit.

“I don’t think he was joking. He said it with venom. That was venom. That wasn’t a joke. In fact, he was nervous when he said it. It was a pathetic delivery,” Trump said on Fox News.

Speaking of pathetic... go away, Donald. And take your hair with you when you leave.
