Your birthday is yummy,
Is what Thief said then,
It tasted delicious,
He burped up my 10…
“Give me my 10,
My birthday’s today,
Don’t mess it up,
Or you’re gonna’ pay!”

Thief laughed at me,
And sang a short song,
It went really fast,
It didn’t take long…
Happy Birthday for you,
Even better for me,
Your numbers taste good,
And I get them for free…

If you were buying a sign that said:

BIRTHDAY

and each letter of the sign cost $10,
how much would the sign cost?
