+Flying home from Frankfurt yesterday via Chicago, as usual I randomly
+selected a shortish looking line in the immigration and customs hall. When
+it was my turn, the agent behind the counter saw the "business" box
+checked on my form and asked who I work for, which is pretty standard. He
+then asked me what I do for HP, but before I could answer, he said
+"No, wait. You've been through here before. I recognize your passport."
+
+I managed to retain my composure just enough to agree that he certainly
+<em>could</em> have seen my passport before. He smiled, stamped my form,
+and waved me through.
+
+My wife wonders why I was so surprised.
