I was just reminded of an somewhat dated oldie but goodie:
Mother Teresa dies and immediately goes to heaven, where she is greeted rapturously. St. Peter himself escorts her on the grand tour, but towards the end of the tour he notes that a halo can't be given to her just yet due to a back order situation at the halo factory that's been going on for a couple of weeks. Mother Teresa, being Mother Teresa, nods serenely and says "I can wait, good Peter."
The next day, however, Mother Teresa is at St. Peter's office doors and she's PISSED. "Halo shortage, my foot!" she yells at him. "I just saw that harlot Princess Diana strutting about and SHE has a halo. I gave my life to my God and spent my days among the poorest of the poor but must wait for my halo, while that overmade-up whore who only did charity work if she could get a photo op out of it ALREADY HAS A HALO! I DEMAND ANSWERS!"
St. Peter remains calm. "My dear Mother," he says, "that's not a halo. That's a steering wheel."
