April 1st. Going for an MRI.
If you are having your brain scanned on April Fools I think you should bring the most obnoxious music possible. If nothing if note appears on your MRI, cool, you have your lucky obnoxious music to thank. If something sinister results you can at least blame that evil fucking dubstep. Win. Win.
Lame. I was told on the phone that I could bring a CD to play. Once I got in the back the tech said "No. Earplugs only. No music."
