The crooner who's never gonna give you up is having his greatest hits collection rereleased by Sony BMG. Rick Astley: The Ultimate Collection will be out at the end of Aprill, which should make for some fun rickrolling gifts. Grand Theft Auto IV comes out around the same time. I can't be the only one with this idea to put the Rick Astley CD in the GTA IV case and give it to an unsuspecting friend. If you can't wait until the end of the month, you can pick up the digital version at or iTunes. Burn it on a CD for your own real-world rickroll.
