When I was going for my meteorology degree back in the 80s, I had a professor who was originally from Germany. One day a student asked him what he thought about the greenhouse effect. He answered in the way he always did when he thought an idea was ridiculous (with a thick accent, of course): "The greenhouse effect is bull!" Barely qualifies as a mild oath, but everything sounded funny when he said it.
Great story. Thanks for sharing.
