The Grouch, by Green Day.
I was a young boy that had big plans. Now I'm just a shitty old man. I don't have fun and I hate everything. The world owes me so f... you. Glory days don't mean shit to me, I drank a six pack of apathy. Life's a bitch and so am I. The world owes me so f... you. Wasted youth and a fistful of ideals. I had a young and optimistic point of view. Wasted youth and a fistful of ideals. I had a young and optimistic point of view. I've decomposed, yet my gut's getting fat. Oh my god I'm turning out like my dad. I'm just a grouch sitting on the couch. The world owes me so f... you. The wife's a nag and the kid's f...ing up. I don't have sex cause I can't get it up. I'm always rude. I've got a bad attitude. The world owes me so f... you.
Hope that wasn't too strong - it's my favourite song to put on when thinking about the witnesses!!
PS - my dad incorporated Imagine into one of his public talks re new system so I found that pretty ironic!
Waiting by Green Day is also good when the aggro has worn off - talks about a new chance to get things right! :-)
