There were plenty of hijinks during Monday's trick-or-treating event at the White House. What else would you expect from Halloween?
What about an instant musical tribute? Well, when President Obama saw a little kid dressed as the legendary Prince, he couldn't help but pay respect to the costume and the musician himself.
Check out the video above to hear Obama sing a few lines from the 1984 hit, "Purple Rain."
And for fun, here's another pic from the festivity.
