I heard this at the cocktail party for the launch of the Galaxy cruise liner, and it amused me so much that I thought I’d share!
Thanks to McPhenius Swain, who devised this!
Our Lindens, who art in the Labs,
Hallowed be thy prims.
Thy Grid-dom come, thy will be done,
On sims, as it is in The Preview.
Give us this day our daily crash,
And forgive us our Spammery,
As we forgive those, who grief against us.
And lead us not, into private parcels.
Amen.
Prim Perfect 
There’s also:
Our fathers who art in California, Linden be thy name… rez us this day our daily prim. 🙂
The original is not made by McPhenius Swain. I recieved the gesture on november 20th 2006 (before mr Swain was born). The gesture made by Myrilla Vixen who is 1,5 year older then mr Swain. It includes also 3 sound bytes and an animation 😉
And its a freebee.
Sorry, I just saw this post in October. Carol is correct, I did not, nor did I ever claim to have created this gesture. It was given to me and has been around for sometime. I simply played the gesture that day 🙂
