I Wanna Fight

This is a letter to you:
"Hey friend, you don't know me,
but you think you do
and I want you too
I'm everybody's friend
and I'm personally connected with you
This song's on the house
and this one's for you
I don't like the way you're treating me,
I want a fight. Settle it right.
I forgot your name but I'd be happy to
beat you to death with a pool cue.
