In the zoo, I think I once saw some. It seems a bit far fetched to believe that a tapir could be mistaken for a cow, a horse and an ass all at the same time, especially in North America where it seems to have been extinct for about ten millennia. I have not read the BoM, so I do not know if there is an allegation that the so called cows were milked or the so called horses and asses ridden, but I wonder whether tapir milk is a good bargain. I'm a bit surprised that, with its pendulous snout, it is not standing in for the elephant too.
As so often seems the case in things like this, the best escape hatch from mendacity appears to be idiocy.
If you smear your shoes with excrement because you mean to, it's very bad. If you do it because you really thought it was Shinola, it's not really a whole lot better.
