When I was in 4th grade, it was simply impossible to imagine a haircut more cool than a mohawk or a flat-top. Luckily, Mary’s Beauty Salon on 18th and Mission offers both of them.
Or maybe this is a reference to the 1988 Japan-only Famicom side-scrolling 2d platform title: “Flaptop and Mohaw”, which Super Mario Brothers 3 was pretty much based on (they just changed the sprites). Seriously, look it up.
