Buffett claims to have seen this line as graffiti in the bathroom of "either Captain Tony's or Napoleon House". It's a send-up of what people write on postcards when they have nothing better to say: "The weather is beautiful, I wish you were here." Of course, if you've ever received such a postcard, you know that generally the writer is too busy having a good time to care less if you were there or not. For me, the Buffett version gets its giggle value from implying that not only does the writer not particularly care whether you are there or not, but he can't even be bothered to sober up enough to get the cliche right.
