I always thought it was:

Something you know: password
Something you are: iris scan
Something you possess: USB key

Absolutely stupid

I can't help but think of:

Something old, something new
Something borrowed, something blue

There are so many positive reasons for ease of use, efficiency and security, it makes absolutely no sense to not escribe narcotics and stimulants, etc.
