Improper comma usage, I think. Should be "OK, boys and girls,..."OK boys and girls, wanna know 2
"wanna" - Adults shouldn't talk like that let alone type like that
"2" - Instead of making the adult level effort of "two"
Ha, I actually don't care about the grammar above but I do find it funny given the point you're trying to make. Just choose to be happy and let things go, your days will go better.
