Shaggy dog story Puns

I saw a shaggy dog on here maybe a month ago. It was about a couple kids in a haunted house. If anyone could put me in the right direction that would be much appreciated

So, a few weeks ago, someone posted a pretty long dad joke. Here's mine--it's what my dad would call a "Shaggy dog story".

The dolphin trainers at the zoo were very upset because the dolphins were very ill and getting worse. An animal shaman told them that he could not only cure the dolphins, but make them live forever--all he needed were some young sea gulls. The trainers immediately set off to find some young sea gulls.

While looking for the gulls, a lion at the zoo escaped. The trainers didn't care--they had to save the dolphins. They found their gulls and were making there way back to the dolphin enclosure when they came across the lion. Fortunately, it was dead asleep, having been hit with a tranquilizer dart--but it was right in the middle of the path. So, they carefully stepped across it, and were immediately arrested. The crime? Transporting young gulls across state lions for immortal porpoises.
