In a Study Abroad talk that SDSU conducted for it's American students who want to come over to NTU for exchange, someone asked, "Are the textbooks there more affordable?" To which ZR blurted out, "VERRRY cheap, VERRRY, VERRRY CHEAP!!!" What causes that kinda response, we don't know for sure. He must have an unhappy childhood or something. But it makes them* red-faced for quite sometime. *I wasn't there fortunately. YL, YT and Mav were. Heheh.
