I prefer the original take on this one as the punchline has a better pun to it

>A horse on a farm falls into some quick sand and is sinking. One of the baby chickens sees and hurries over to the farmers truck and backs it up to the edge of the quick sand. He uses the winch to pull the horse to safety > > >a few weeks later the baby chicken slips amd falls into the same quick sand. The baby chicken calls out to the horse to get the truck. The horse acting quickly, simply stands over the quicksand and squats down and the baby chicken is able to grab the horses penis and pull himself free. > > >which just goes to show, if you're hung like a horse you don't need a big truck to pick up chicks
