Q: Have you heard the joke, the punch line to which is, 'We pronounce it "Ohio" here'?
A: Uh, no, I don't think I've heard that one.
Q: Oh! Well, a fellow from the Midwest was traveling through New England. He was traveling by train, and entered into a conversation with the other people in his compartment, one of whom asked him, 'Where are you from?' 'Iowa,' he responded. 'Oh, Ohio? I've never been there,' said the other passenger. 'Ah, no, sorry, I'm from Iowa,' he said. The other passenger smiled condescendingly and said, 'We pronounce it "Ohio" here.'
At this point, Maria would break into uproarious laughter, and her delight was so evident that you couldn't help but join in. It was an oddly effective way of telling a joke.
christychristy then said something about 'the Jake way of telling a joke'. It had never really occurred to me that I had a way of telling a joke, so I asked what my way was. She said that I tended towards the deadpan, and that it wasn't always obvious that I had, in fact, told a joke. That sounds about right.
