I worked in a Japanese company years ago.. (This is in the USA, mind you...)
On December 7th, I overheard one Japanese manager talking with another Japanese manager:
"Do you know what day it is?"
"No"
"You know, 12th month, 7th day."
"huh"
"You know!"
"Nope..."
"You know - Tiger! Tiger! Tiger".
"Ahhh - soo"
