An old woman gives glory to God

 An old woman manages to catch the bus just before it left, exclaiming "Glory to God, I made it!"

The bus driver tells her, "Comrade, you can't say that anymore! You have to say 'Glory to Comrade Stalin' now!"

"Forgive me, I get forgetful sometimes at my age," the woman replies. "But what do I say if, God forbid, something happens to Comrade Stalin?"

"Then you can say 'Glory to God!'"
