(Note: It is a custom in Indonesia and nearby countries for people to hit a stick to wake people up so they will eat the sahūr breakfast meal, before the break of dawn and the start of the daily fast. The stick is called a “kentongan”.
A similar tradition exists in the Middle East, but with someone in the neighbourhood beating a drum: the drummer is known as a “mesaharati”, and even with alarm clocks he is still a well-known tradition.)
Yep.
hollow sticks?
Maybe because sticks are louder than pans and bowls?
There was no innuendo intended here: it’s a traditional custom in Indonesia. In a tropical climate as this in the olden days, what else would they use to wake people up? (Pans? Bowls?)

Not the kind of morning wood one typically expects
