The U.S. Army Infantry soldiers in Kunar Province, Afghanistan, aren't above having a little fun while stuck overseas, and their "Call Me Maybe" cover is among the best we've seen --  it showcases their day-to-day life for those of us who have no clue.

Of the star-studded performances at last night's Olympics closing ceremony, one of the most understated was Ed Sheeran's cover of "Wish You Were Here," by Pink Floyd.
