When Bottles Dance

Read this in one of Khushwant Singh's joke books many many years ago. Quoting from (my not so good) memory:

Agar dum hain dua mein Maulvi,
to is bottle ko hila ke dikha.
Agar nahin, to do ghoonth pe,
Aur bottle ko jhoomta dekh.

(If there's power in your prayers,
make this bottle move.
If not, take two sips,
And watch the bottle dance.)
