Between Cinco de Mayo and National Day of Prayer, it's been a week of non-stop partying, and it's not slowing down anytime soon. In case you weren't aware, the first Friday of May is always No Pants Day. It's an excuse to make casual Friday all the more casual, and hopefully, take the day a little less seriously.

Some sneaky ladies or kilt-touting men may think they can get away with just a skirt or dress. This ideology is rejected by No Pants Day, because the entire occassion is to celebrate the freedom of rejecting any sort of leg covering. If you're worried about looking unprofessional at work, either cite observance of an obscure, oft-persecuted religion, or perhaps just play dumb and act like you were too hungover to remember pants (it's not that hard to pull off).

Like Halley's Comet, the tradition dates back to 1986, and has been actively promoted by NoPantsDay.com for 10 years. So tackle the taboo and toss the trousers — you don't have to let it all hang out, but you know you've wanted to show off your favorite pair of pink panties or silk boxers for awhile now.
