Granted - Everywhere you go, everyone around you hears your "theme". You thought it would be cool - like the Imperial March, or something along those lines... Unfortunately since you didn't specify what song would be your theme, everywhere you go, every minute of the day, everyone around you (including you) hears the Barney song - only it's sung by William Shatner instead of Barney. It was cool maybe the first time... but after 100 listenings, you decide to end your own life by using your mental power to control an meteor to crash on yourself. You are certain this will end the song... sadly however, the song doesn't end for you as you are eternally in a personal hell where the only thing you hear is William Shatner singing ("I love you, you love me...") Be careful what you wish for...
I wish for naught.
