MLK day is good for figuring out which guys can grow good facial hair. There are lots of bros walking around with faces like it’s the day after the Rapture and God chose razors and warm water. Some guys (e.g. Brett Favre) can really pull off this look but other people just look like their face is dirty. Either way it’s a nice change of pace, and usually someone takes the opportunity to start a “growing a beard” phase, with typically hilarious results.
