Grant had also spent his weekend at the beach and was showing off a pretty, pretty nasty sunburn, which he was pretty excited about because it gave him a chance to flex his calves...
Look at the color of Grant's face. I swear to God I didn't alter the contrast or anything. I wish I had the audio file of him a few hours earlier all saying "It's cloudy, dude! You don't need to wear lotion when it's cloudy out!"
