I have seen the seven wonders of the world and if there is an eighth I have seen it too. I have walked through the most wonderful parks of every civilized and uncivilized country in the world. I have slept in the finest beds of the most fashionable hotels of the biggest cities of the best countries. I have eaten the tastiest foods on Earth, I have spent long afternoons in the most beautiful gardens of the richest people on Earth drinking green tea, reading the cheapest novels and smoking the most expensive cigars. I have played poker with the most famous people - with the Prince of Wales ad with the Countess of Strasbourg. Seven of the wonders I have seen, but the best  place for me is Beale Street.
