User blog comment:Sean B./Can anyone here please find a video of the full Mermaid Slapping Jack Sparrow Deleted Scene ? *Not from in the Featurettes about Pirates 4 though.*/@comment-4898132-20111114064047

I'm sorry, mate, but I don't think such a video exists. If it's not on the DVD or anything else, it's not going to appear for quite a while. The only places we can see said scene, either as a whole or in pieces, is...
 * 1) The second OST trailer
 * 2) The "Blackbeard, Zombies, Mermaids" Featurette

Other than those 2 OST-related footage, the mermaid slap scene is NOWHERE to be found. I'm sorry, but this discussion seems pointless as the scene appears neither in the film or the DVD itself. It's been done, it's over. All that can be done now is that we wish it was in...nothing more.
