Intro:  / G- (320003@1)- - / - - - - /



G (2)

Once a year we celebrate

C (x32010@1)                   GWith (320003@1)stupid hats and plastic plates

G (2)
The fact that you were able to make

C (x32010@1)      G(hold) (320003@1)Another trip around the sun

G (2)
And the whole clan gathers round

C (x32010@1)                     GAnd (320003@1)gifts and laughter do abound

G (2)
And we let out a joyful sound

C (x32010@1)                    G(hold) (320003@1)And sing that stupid song

G (320003@1)          C (x32010@1)           G(2) (320003@1)Happy birthday!  Now you're one year older!

G (320003@1)          C (x32010@1)           G(2) (320003@1)Happy birthday!  Your life still isn't over!

G (320003@1)         C (x32010@1)            GHappy (320003@1)birthday!  You did not accomplish much

G (2)
But you didn't die this year

C (x32010@1)             GI (320003@1)guess that's good enough



/ G- (320003@1)- - / - - - - / C- (x32010@1)- - / G(hold) (320003@1)/

G (2)
So let's drink to your fading health

C (x32010@1)            GAnd (320003@1)hope you don't remind yourself

G (2)
The chance of finding fame and wealth

C (x32010@1)            G(hold) (320003@1)Decrease with every year

G (2)
Does it feel like you're doing laps

C (x32010@1)         GAnd (320003@1)eating food and taking naps

G (2)
And hoping that someday perhaps

C (x32010@1)                 G(hold) (320003@1)Your life will hold some cheer

G (320003@1)         C (x32010@1)                    G(2) (320003@1)
Happy birthday!  What have you done that matters?

G (320003@1)         C (x32010@1)                    G(2) (320003@1)Happy birthday!  You're starting to get fatter

G (320003@1)               C (x32010@1)          GHappy (320003@1)birthday!  It's downhill from now on

G (2)
Try not to remind yourself

C (x32010@1)             GYour (320003@1)best years are all gone

/ G- (320003@1)- - / - - - - / C- (x32010@1)- - / G(hold) (320003@1)/



G (2)
If cryogenics were all free

C (x32010@1)                 GThen (320003@1)you could live like Walt Disney

G (2)
And live for all eternity

C (x32010@1)              G(hold) (320003@1)Inside a block of ice

G (2)
But instead your time is set

C (x32010@1)         GThis (320003@1)is the only life you get

G (2)
And though it hasn't ended yet
    
     C (x32010@1)               G(hold) (320003@1)Sometimes you wish it might

G (320003@1)            C (x32010@1)               G(2) (320003@1)Happy birthday!  You wish you had more money

G (320003@1)            C (x32010@1)                  G(2) (320003@1)Happy birthday!  Your life's so sad it's funny

G (320003@1)            C (x32010@1)               GHappy (320003@1)birthday!  How much more can you take?

G (2)
But your friends are hungry

C (x32010@1)            GSo (320003@1)just cut the stupid cake

G(2) (320003@1)                     A7(2) (x02020@1)Happy birthday!  Happy birthday!
           C(2) (x32010@1)        D7(2) (xx0212@1)
