You better put me in the strange sense of humor category. Reading this bit had me almost suffocating from laughter. BANZAI!
I used to do something else when around Japanese businessmen (not here in South Florida since we don't get many such folks here). I call it Karate Hara-Kiri. I would jump up in the air and scream "HARA-KIRI!" while karate choping my own neck with both hands. That was also an easy laugh getter from the Japanese businessmen. I don't know why I like making those folks laugh. Maybe it is because they look so serious in their business suits and then change so completely when you get them in laughing convulsions. I just like the contrast.
