O-bow-ma, Har!

From NB:

But PBO's bow seemed to go beyond the perfunctory head-nod that in the circumstances surely would have satisfied, say, Japanese etiquette.

What is it with our head of our state and Commander-in-Chief that sends him diving toward his shoes whenever a foreign dignitary hails into view? Will the MSM cover this latest installment in the adventures of Pres. O-bow-ma?

"O-bow-ma" I love it.
