Why do you wear different underwear every day?
I am running almost every day after work, so even though I am definitely not a neat person, I can't just sit in sweat-wet underpants at home... That would be too much.
I remember running out of fresh underpants once, few years ago, and it was a very hot summer day, so I used a t-shirt as underpants. Used a saggy one, so my legs would go through the armholes... My ex wife have been very disappointed with me when she got back from work. I called this double t-shirt combo - "a Jesus set", cause I looked like him, when he had them rags on while hanging on the cross.
Anyway, it's trendy now to take pictures while shitting at work, like Harlem shake back in the days and such. You should all join the fun guys. All the celebrities are tweeting their shitting pictures and you are living in the cave and don't know shit about shit.
