Oh...
It's your happy birthday
Here's your happy birthday song
And on your happy birthday,
Nothing can go wrong

I can tell that you're all [bad word] 'Cause you've been around a while
Just because you're old and [bad word] Doesn't mean you shouldn't smile
Because...

It's your happy birthday
Here's your happy birthday song
And your birthday best be happy,
'Cause you won't be around for long!
 [bad word] 

Sylvia: So, try not to be so sad
'Bout your impending doom,
Someday, we'll light birthday candles
On your frigid tomb

Wander: Oh...
It's your happy birthday
Here's your happy birthday song
And your birthday won't be happy,
'Til you all sing along!
Everybody!

Watchdogs: Oh...
It's your happy birthday
Here's your happy birthday song
Wander: Just the pit monster!
(The monster mumbles in time)

Everyone: I can tell that you're all [bad word] 'Cause you've been around a while
Just because you're old and [bad word] doesn't
Wander/Sylvia: Mean you shouldn't...
Wander: What's that I see? Ohhhhhhhh...!!!
Wander/Sylvia: Smile!
 [bad word] 

Wander: Happy birthday, Hater!
