Unhappy Birthday

I've come to wish you an unhappy birthday
'Cause you're evil
And you lie
And if you should die
I may feel slightly sad
(But I won't cry)

Loved and lost
And some may say
When usually it's Nothing
Surely you're happy
It should be this way ?
I say "No, I'm gonna kill my dog"
And : "May the lines sag
the lines sag heavy and deep tonight"
