ROTHFLMAO!
I didn't mean to open a can of worms here(or snakes in this case). The battle of the snakes has been going on for over 100 years. In the United States, it is difficult to find the Rod of Asclepius as it is frequently trademarked into "Association Trademarks"
This battle has raged since the U.S. Army (which has now switched back to the Rod of Asclepius) first used the Caduceus before WWI.
Here is a clip that rages on in the medical communities
.
Despite widespread acceptance of the caduceus as a medical symbol in the
United States, it has been observed that the rod of Asclepius has "the more ancient and authentic claim to be the emblem of medicine".
[14] Most attempts to defend its use in a medical context date from the last quarter of the 19th century through the first quarter of the 20th, and have been characterized as "based on flimsy and pseudo-historical research".

In a survey of 242 logos used by organizations related to health or medicine, Friedlander found that professional associations were more likely to display the rod of Asclepius (62%), while organizations with a commercial focus were more likely to use the caduceus (76%). Hospitals were an exception (37% used a staff of Asclepius whereas 63% used a caduceus).
