I mean, I'm GLAD mustaches are popular. Obviously I like them too, because I wanted a necklace of one (I had seen them all over the internet and I just HAD TO HAVE ONE). They're a hipster staple. They're very trendy.

^^ Even Christofer Drew Ingle of Nevershoutnever likes them.
But WHY ARE THEY POPULAR?! I guess we'll never know.
