A poem about THAT mole

I am THAT mole!
You know, the mole that you can always see
You always no you can't miss me
I'm so huge I take up a whole cheek
I'm here every day of the week
Cover me up? You can try!
You'll be so frustrated you might even cry
Whose mole am I? Can you not tell?
Whose cheek it was I chose to dwell?
