Donald Trump isn't one to forget. Or one to overlook the chance for a good publicity stunt.

"Today I sue Bill Maher," Trump told Fox & Friends on Monday.

At issue: Last month, Maher made an appearance on Jay Leno's Tonight Show and quipped that Trump must be "the spawn of his mother having sex with an orangutan."

Maher was mocking Trump's offer to give $5 million to the charity of Barack Obama's choice if the president released his college paperwork, by saying he would do the same if Trump supplied proof that he is not descended from an ape.
