- Aimee Thanatogenos... First lady embalmer of Whispering Glades.

- Oh, thank you, blessed reverend. Thank you.

- That will be all. Thank you.

(Miss Thanatogenos giggling)

- I can't believe it. Oh, Mr. Joyboy!

- If I may intrude a personal note, this does call for a little celebration, don't you think? I wonder if you would do me the honor of having supper with me this evening.

- Oh... I don't know what to say.

- Well, I wish you'd come to my home, Miss Thanatogenos. Yes, I claim the right and the very great privilege of introducing the first lady embalmer of Whispering Glades to my mom.

- The first lady embalmer of Whispering Glades.

- May I consider it definite, then?

- OK.

- Well, 7:00, then? Congratulations.

- The first lady embalmer of Whispering Glades. Lady embalmer of Whispering Glades. The first lady embalmer of Whispering Glades.
