Fanny Packs. Why?

So I'm at work working on this winter reset for at Home Depot (where I work) and all of a sudden I see this guy I work with (who is clearly one of the dumbest, most useless people I've ever met, and he's like 45, and has the work ethic of a spoiled 15 year old) wearing a fanny pack. Yes a fucking fanny pack. I felt like I somehow traveled back to 1995 with Doc Brown looking back at how idiotic we all were for wearing these things and sharing a good laugh and a beer afterwards. Unfortunately, it wasn't 1995 or any year before that it was 2010 and I am seeing before my eyes a grown ass man wearing a fanny pack. I'm starting to think it's an old person thing and they're still living in the 20th Century waiting for Murder She Wrote or Fraiser to come on. Naw, fuck that. There is no excuses for someone to wear a fanny pack this day and age. I mean, really, are these people going to Six Flags or Disney World everyday? What could you possibly need so badly that wouldn't fit in your pockets? This guy at work is given a damn apron to hold shit he needs and his keys and wallet are in his pants pocket. What the hell else would you possibly need to carry a fanny pack around for? Also how could you look yourself in the mirror knowing that you willing are going to go around and where a fanny pack? It's not like you're a pro wrestler or something. Also what's up with those guys buying jeans too tight to put there damn keys and wallet in there pants? You don't see football players doing this. I mean what the hell?
