I'm glad that I had already purchased Volume 7 separately prior to the 2013 pressing, which was the first to omit the two 3D shorts. It was actually only recently that I realized that THE THREE STOOGES ULTIMATE COLLECTION 20 DVD Set that I bought dirt cheap (Under $32 CDN total, via Amazon Canada!) in January 2014, only had the 2D versions of SPOOKS! and PARDON MY BACKFIRE.
I think it would be great if Sony could redo the 3D shorts for a future Blu-ray release for the above collection, though I don't expect it!
