EVERY GODDAMN TIME

Among the few things in Super Mario Bros. 3 I can't do is the spinning match up game thing. It's as if it lets you get the first two lined up easily, and then BAM, it hits you with the wrong one. Every goddamn time. The other things that I can't do are use the Tanuki Suit to its full potential, and FINISH THE DAMN GAME.
In this house, we've been playing Mario Bros. 1 and 3 for like twelve years, and not once have either of them been completed.

It's rage-inducing.

Especially given there are people out there who can finish the game in six minutes or less.
