30 days of MCR - Day 4: Your favourite song from "Three Cheers for Sweet Revenge"

allright, I've been thinking of this all day, and I love all the songs in the album no exceptions...
But the four that I love the most are, Helena, I'm not okay (i promise), Thank you for the venom, and I never told you what I do for a living... but I only can put one video... so it's 'I never told you what i do for a living'
I've loved that song since I first heard it.
