Jimmy Fallon and Maroon 5 went undercover in NYC giving a surprise performance of "Crazy Little Thing Called Love" and "Sugar" and it is AWESOME. It always blows my mind when celebrities do this and people have absolutely no idea who they are. I mean, Adam Levine has the actual voice of an angel, HOW DO YOU NOT KNOW IT'S HIM??????? The people who just walked on by paying 0 attention to them probably hated themselves when they watched Jimmy Fallon last night.
