Know about sex? Good, 'cos we know nothing. Happy to have Mario and Luigi fill us in on this like puberty and STDs in this NSFW clip. The yuk-yuks at Seriously Hilarious cobbled together this using footage from retro Saturday morning cartoon Captain N: The Game Master. It's actually jam packed with helpful info, but mark my words: you will never look at Toad the same. Like ever. Brian Ashcraft

Thanks, Chris!
