Ellen DeGeneres invited Kanye West to chat on her talk show, and Kanye West accepted the invitation, even though he clearly had every intention of talking as little as possible. Ellen tried to make Kanye personable by bringing up his two young kids and joking about how Ellen helped pick out Saint's name. Kanye did not bite.
Poor Ellen, all she wanted was a little recognition that she's a great friend. And Kanye couldn't give that to her.
He could, of course, praise North West for being advanced for her age, a claim that confirms Kanye is a indeed a father because every parent says that about their kid.
Though Saint's abilities weren't mentioned, this kid is probably also advanced.
