I’ll do it.
Here is the plan... I tie a length of black nylon thread to a safety pin.
I’ll hook the pin in the door screen, the take the line out to the bushes, I rosin the line and pull it tight.
I get that screen door to rattling until Obama runs to the door and throws it open. I let the line go slack and he cranes his head round till he decides there is no one there.
Rinse lather and repeat till he is getting chapped.
Then You place the gift and torch it, and I set the screen to rattling once more.
He’ll stomp that sack dry. I guarantee!
Ah, you’ve done this before! :-)
