You know how annoying it is when parents name all of their kids with the same first letter? "Hi, meet my kids Brittany, Blake, Bryan, Bailey, Bernie, and Benjamin." Ugh, those people. Well, Clemens did the same thing, only worse.
He gave all of his kids names that started with 'K' because, you know, he, like, strikes people out. Even more obnoxious is the fact that his kids' names (Koby, Kory, Kacy and Kody) are actually 'C' names, not 'K' names at all. You can't spell Kory and Kody with a 'K.' Right? Unless, of course, you're a total jackass.
