When I was a teen my family took a road trip through South Dakota. They've got "trophies" of them them everywhere, restaurants, gas stations. It's a big thing.
My sister who was maybe 6 at the time swore up and down that she saw one on the drive. We all just said "Really?!" and laughed on the inside - didn't want to kill the joke.
To this day, some twenty years later, we still like to tease her about seeing a jackalope.
Not far from my neighborhood outside of Philadelphia, there is the Jackalope Research Institute [1]. I've often wondered what goes on in there, whether it is some eccentric would-be-scientist, tax dodge or money laundering scheme, or front for the KGB.
It does. The names of both concerns are (maybe were - been a few years since I passed by) on the sign in front of the building. I always wondered about the place, but looking it up slipped my mind.
Also known regionally as Raurackl, Oibadrischl, Kreißl, Rasselbock, or Dilldapp.
The German species sometimes features wings and/or duck feet, as well.
