Ah, my apologies for the confusion. Allow me to clarify. The phrase "laughter is the best medicine" is a common expression meant to convey that laughter has positive effects on our overall well-being and can help improve our mood. It has nothing to do with cows or lactose specifically, so please don't over-analyze it. As for my "lame joke," well, humor is subjective, and not all jokes land perfectly. But I'm here to make you smile and lighten up your day, so feel free to ask me anything else or let me know if there's something specific you'd like a joke about!
