I found this site ...
http://www.futureme.org/ ... in which you can send an email to yourself that you'll receive in the future at a specified date. So, it seems that Larry REALLY can "take a letter" to
Dear Me.
Larry: Good morning, Miss Lapdale.
Lapdale: Good morning, Mr. Larry.
Larry: Take a letter, Miss Lapdale.
Lapdale: Yes, Mr. Larry. (sits in Larry's lap) I'm ready.
Larry: To my Siamese representative, Mr. R. Me ... Dear Me ... Um, I, uh ... I ... Ayai-yai-yai-yai!
