A not well-known glitch: P-Wing vs. Bullet Bills (Super Mario Brothers 3)

Many gamers seem unaware that Bullet Bills can be beaten with a simple tail attack in SMB3, as if you were playing baseball using the Bullet Bills as balls and your tail as a bat; more so, there's an almost unknown glitch that allows you to beat Bullet Bills when you fly high with a P-Wing over them and press the B button.
