This was Bill's present from Germany. There is a quintessential Hessian dialect phrase that means approximately "How's it going mate"--in a sort of laid back friendly way--and that phrase is "Ei Gude" --the Gude being hessian for good guy...this cup from the Frankfurt tourist office is a geeky pun on that phrase..."Ei" and the english "i" are pronounced the same way. So its an inside Hessian joke...funny.
