You say it's your birch day;
It's my birch day too, yeah.
They say it's your birch way—
We're gonna have a good time.
I'm glad it's your birch day:
slappy birch day to you.

Yes we're gonna make a smarting party!
Yes we're gonna make the smarting hearty!
Yes we're gonna make the smarting hearty!

I would like you to spank (birch day);
I will th-th-th-thank (birch day).
In turn, you I will spank (birch day).
Spank!

I hope that I can bank (birch day)
on you to sp-sp-spank (birch day);
Up the tempo, please crank! (birch day)
Crank!

Enjoying my birch day;
you like your birch day too, huh?
What’s better then birch day
for me? To have a wood time.
Now, let’s make it lurch day—
gladly lurch into you.
