The junior officers challenged the senior officers at an Air Force Base in North Carolina to see who would donate the most blood.
After trying several times to locate a vein in the left arm of a young first
lieutenant, the medical technician applied a Band-Aid, and then inserted a
needle into the right arm, drawing blood this time, and then put a Band-Aid on
that arm as well.
As he left the collection facility, the lieutenant passed a colonel. Noting the
two bandages, he looked at the first lieutenant and shook his head, saying,
"I knew you young guys would find some way to cheat."
