Donald Trump walks up to President Obama... He asks, "Obama my man, how did you manage to put together such a wonderful team? Tell me your secret." Obama smiles and replies, "Well, the first thing that you have to do, Mr Trump, is to surround yourself with intelligent people." "Well how do I do that?" asks Trump. "Simple," Obama replies. "The way I do it, I always ask them one simple question." He turns around and yells, "Joe! Get in here!" Joe Biden saunters into the the room. "Joe," Obama says, "Mr Trump here wants to know how I know if someone is intelligent. So let me ask you this: Who is your father's son?" Joe thinks about it, and replies, "That would be me, Mr President." Obama nods. "Excellent, that is correct! See, Mr Trump?" Trump hates to admit it, but he is impressed. "Very good, Mr President," he says. "Thanks for the advice." Trump returns to his office at Trump Towers and decides to test Mr Obama's method. He picks up the phone and rings Chris Christie. "Hello, Chris?" "Yes Mr Trump?" says Chris Christie on the other side. "I want you to answer a simple question. Who is your father's son?" Chris is perplexed. After a few moments of silence, he replies, "I'll get back to you tomorrow, Mr Trump." and puts down the phone. Worried about disappointing Trump, he calls the smartest person he knows, Bill Gates. He dials Bill Gates' number. "Hello? Bill?" "What is it Chris?" "I need to ask you a question." Bill Gates gets annoyed. "Look, Chris, no more stupid questions, ok? I have a meeting in 15 minutes and I've got to get ready." "Right, right," says Chris in a flurry. "Who is your father's son?" Bill is furious. "IT'S ME OF COURSE YOU FAT PIECE OF SHIT!" he yells and slams down the phone. The next day, Chris meets Donald Trump for lunch. "So, Chris," says Trump. "You said you'd get back to me on this. Who is your father's son?" Chris smiles triumphantly. "Why, Mr Trump, it's Bill Gates, of course!" Trump is enraged and slaps him in the face. "IDIOT!" he yells. "IT'S JOE BIDEN, YOU STUPID SHIT!"
