Old But Still Barks

Alright, you knucklehead, listen up! This meme shows a dude who looks a lot like Mr. Beast, holding what seems like a power tool, then an old, rusty gun. The text 'Mr. Heat' and 'It's old. But it still bark!' is playing on the idea that old guns can still fire, or 'bark'. It's kinda funny 'cause the power tool on the left looks vaguely like a futuristic weapon, but then the right picture is a real, old-school gun. You probably thought it was just some dude holding two random things, didn't you, you silly goose?
