P is for Precocious

After a round of singing the Sesame Street classic "C is for Cookie," and including variants like "T is for Tessie":

Tessie: C is for cookie, that's good enough for me... C is for cookie,
that's good enough for me... P is for pneumonia, that's good enough for me...

Tessie's Mom: Did she just say "P is for pneumonia?"

Tessie's Dad: Yes, she sure did.

Tessie: I'm a strange child.

And there you have it.

(Credit/responsibility/blame for this must go to the Barenaked Ladies song "Crazy ABCs" on the Snacktime album, which Tessie greatly enjoys.)
