While visiting India , Donald Trump is invited to tea with Abdul Kalam. He asks Kalam what his leadership philosophy is. He says that, it is to surround himself with intelligent people. Trump asks how he knows if they're intelligent. "I do so by asking them the right questions," says Kalam. "Allow me to demonstrate. " Trump watches as Kalam phones Manmohan Singh and says, "Mr. Prime Minister, please answer this question: Your mother has a child, and your father has a child, and this child is not your brother or sister. Who is it?"

Manmohan immediately responds, "It's me, Sir !" "Correct. Thank you and good-bye" says Kalam. He hangs up and says," Did you get that, Mr. Trump ?" Trump nods: "Yes Mr. President. Thanks a lot. I'll definitely be using that!"

Trump, upon returning to US, decides he'd better put Mike Pence to the test. Trump summons him and says, "Mike, I wonder if you can answer a question for me." "Why, of course, Sir!. What's on your mind?" Trump poses the question: "Uhh, your mother has a child, and your father has a child, and this child is not your brother or your sister. Who is it?"

Mr. Pence was puzzled and finally asks, "Can I think about it and get back to you?" Trump agrees, and Pence leaves. Pence immediately calls a meeting of all staff, and they puzzle over the question for several hours, but nobody can come up with an answer. Finally, in desperation, Pence calls Ted Cruz and explains the problem. "Mr. Cruz, your mother has a child, and your father has a child, and this child is not your brother or your sister. Who is it?"
Cruz answers immediately, "It's me, of course."

Much relieved, Pence rushes back to Donald Trump, and exclaims, "I know the answer,Sir! I know who it is!
It's our Ted Cruz!" And Trump replies in disgust,

"Wrong, it's Manmohan Singh!"
