Shitty. I could only find the live version. This song is "Personal Space Invader" by Andrew Jackson Jihad off of the album People Who Can Eat People Are the Luckiest People in the World. The entire song is good, but the last part of the song is what really gets me every time.
Welcome to this world have as much fun as you would like
While helping others have as much fun as you’re having
Be kind to those you love
And be kind to those you don’t
But for God’s sake you gotta be kind
And respectful, because we’re all one soul
Be the best fucking human that you can be
Yeah, man! That's what life is all about!
