I just saw a classic Hebrew National commercial that shows a cow, split in two by a dotted line. They claim they are kosher because they use only the choicest cuts of meat, and fill in the front part of the cow. The tagline? No ifs ands or butts!
After all, who wants to eat a cow's butt?! See, isn't that a much better excuse Ashkenazim can use for not using the back end of the cow, rather than they don't like the idea of traiboring?
Please note: The views in this post do not necessarily reflect my own view, which is: There is no good excuse for not utilizing traiboring. It would make available twice the amount of meat there is now!!!
