The Mario Bros. Guide to Grooming Your Moustache
The comic opens with Mario and Luigi in a Barber shop, where Luigi grooms Mario's moustache into different styles. Luigi's moustache styles are all ridiculous, however, causing Mario to become more and more enraged. Eventually, Mario begins to chase Luigi around with a pair of scissors, threatening him with various painful sounding moustache styles.
