Sign of Unintelligent Life

We spotted this sign in a Bath, NY yard on our return trip from Buffalo last week. The unusual take on "Beware of the Dog" begs the question:

Is the pit bull more or less of a threat than a pit bull without AIDS?

Then again, the same homeowner was proudly displaying a "WAL*MART YES" sign on the same front lawn, so we guess we'll consider the source before we expend much energy pondering it.
