Ritualistic nonsense.

The Muslim prostrates himself five times a day and faces Mecca to talk to his imaginary friend.

The Jew bangs his head on a stone wall whilst wailing to his imaginary god and posting notes to him into the cracks.

The Christian looks up to the sky, crosses himself and asks his imaginary friend to help his football team to win.

The Atheist watches in bemusement and shakes his head at the ritualistic nonsense.
