In Chelm

In Chelm, the shammes used to go around waking everyone up for minyan (communal prayer) in the morning. Every time it snowed, the people would complain that, although the snow was beautiful, they could not see it in its pristine state because by the time they got up in the morning, the shammes had already trekked through the snow. The townspeople decided that they had to find a way to be woken up for minyan without having the shammes making tracks in the snow.
The people of Chelm hit on a solution: they got four volunteers to carry the shammes around on a table when there was fresh snow in the morning. That way, the shammes could make his wake up calls, but he would not leave tracks in the snow.
