During a Halloween event at the White House, President Obama was inspired to sing Prince's Purple Rain.

A little boy dressed as Prince was in line to get treats from the President (I wonder if the White House hands out full-size candy bars?) when Obama spotted the little Prince and suddenly broke out into Purple Rain.

President Obama is always great with kids, and you can tell he loves his time with them, his singing, on the other hand, isn't that great.
