Well, my daughter and I took that silly llama song to heart.....

http://www.albinoblacksheep.com/flash/llama.php

and decided to use part of it as a clue when we want to have a clandestine
meeting! Perhaps others here might like it also!

There is a part in the song that asks:

"Is it made of lemonjuice?"

To which the other replies the next line from the song:

"Doorknob. Ankle. Cold."

Very Max and Agent 99, Silly, and fun and who else out on the trail is
possibly going to think to reply that way?
