I will refer your question to the Department of Redundancy Department.
In the same (but no longer remotely on-topic) vein, one frequently
hears the experession "and et cetera", which is correctly criticized
as being redundant. What is not well known, is that "et cetera" is
latin for "and the rest", but "cetera" is a contraction of the greek
"kai heteros", meaning "and the rest". So Romans were being redundant
in putting "et" in front of it!
The literal translation of "and et cetera", then, is "and and and the
rest". ;-)
