who's on first?

(heard in stage whispers after something gets knocked behind the sofa):

ozzie: "what was that?"
zoe: "it was an accident."
ozzie: "yeah, but what was it?"
zoe: "it was an accident!"
ozzie: "i know! but what WAS it?!?!"
zoe: "it was an ACCIDENT!!!"
ozzie: "i KNOW! but what WAS IT?!?!"
zoe: "AN ACC-I-DENT-TUH!!!"

do you know what a "pornet" is?

zoe: "...a pornet... doesn't have a stinger, but it does have a little pig nose and very small wings and it flies around. and it eats pig food."

(it sounds like it is related to the Airbug.)
