I was shopping for your Birthday,
I wanted to bring you cheer,
I began to think of presents
that you might like this year.

As I stood there thinking
a fart built up inside,
I tried hard to suppress it
and my eyes got really wide.

I looked around with a smile
and my motor began to run,
right there in the store
it was a very loud one.

It sounded like a motorcycle
running through the store,
I gave up on my search
and headed for the door.

I was about to leave the store
and give up on your day,
still wondering what to do
for your Birthday anyway.

Then what sounded like a car
I thought was in my head,
but with every contagious smile
a fart will also spread.
