snail and three pebbles 

From Comedy Central's "Halfway Home", a ceremony in which one picks up three pebbles of differing size with one's ass cheeks.
One must then walk forward, and drop the pebbles, one by one, smallest to largest, into somebody's hand.

"You must perform the ceremony of 'the snail and three pebbles' to prove you are my son"
