Curious George always wondered what the Man in the Yellow Hat has been smoking lately that smelled so good. And so George then sneaked into a weed cabinet which the Man in the Yellow Hat has left unattended, grabbed a few J's and a lighter and then started enjoying himself. He could not stop afterwards. What a grass monkey he now is!

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
