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."
