only the sexiest man alive or dead. anyone named Mr. B is easily a god amongst mortals. we should all be humbled by his presence. he is the most powerful entity of infinite beauty within the unending cosmos that is this realm. you should totally do what he says. Art teachers named Mr. B especially, he'll destroy you otherwise
Mr. B told us to draw the definition of "magnificence", so obviously i drew him.
