All those years. All those years spent crossing my arms and pulling from the bottom, or yanking the back of the collar over my head, wasted. Imagine how much more time I'd have right now to watch instructional YouTube videos if I'd seen this instructional YouTube video when I was but a lad?
With summer coming, and long days ahead sitting sweaty on a couch playing [game you like], don't consider this a joke "lifehack" video. It's education.
Course, it helps that this is a thin dude wearing a loose cotton shirt. YMMV. I just tried it on the football shirt I was wearing, for example, and it did not go well.
