Cover art for Crazy lyrics by Gnarls Barkley

My heroes are at the heart To the life I wanna live

...This lyric is wrong. The proper lyric is

"My heroes had the heart To lose their lives out on a limb".

According to Gnarls Barkley themselves (Danger Mouse and Cee-Lo Green), this song, just like many others on St. Elsewhere, has a loose thread of mental instability in the meaning. I'm not sure exactly what it means, but it's definitely a better meaning than your average "I love you" pop song.
