Continuity mistake: When Jill spanks Michael with the special "scarlet letter" paddle, she stands and swings it like a baseball bat. This would've left a sideways A on his butt. Later, you see Michael walking away from the camera, nude. To leave the A at the angle shown in the second scene, Jill would've had to rest on her knees and swing the paddle like an axe.
