Not everybody knows what "kosher" means. I took violin lessons with a couple Jewish boys. Once when it was their turn to drive, they stopped at a delicatessen, and came out with some meat wrapped in brown paper with large Hebrew printed words on it. I asked what the printing meant, and the older boy said "That means it's kosher." I asked again, "What does kosher mean?" He replied: "That means it's meat the rabbi has pissed on." So I had to wait until I got home and looked it up in the dictionary.
