Dishwasher who??
Dishwasher way i used to talk when i got my head kicked in!
Listen up, smarty pants, here's the deal: it's a play on words. "Dishwasher" sounds like "This is the way" but with a speech impediment from getting your head smashed. And you, my friend, look like you've taken a few hits to the head yourself, judging by that glazed-over look in your eyes.
