I meant to post something on Pantsu Day earlier this week, but didn't get it done. So then National Underwear Day comes around just three days later, giving me a second chance!
It appears that today is Pantsu (Panties) Day in Japan, because 8/2 can be pronounced (in Japanese) to sound like pantsu. It's the same sort of thinking that made 5/4 into Star Wars Day here in English-speaking countries...
