Why didn't the chicken cross the road?
Well, because she'd just come from there in the last lame joke and was fed up. It was high time she took her life into her own two ha.. wings and became independent of the lame joke community! So off she strutted down the street, not caring which direction she took as she had no clear destination just yet. After so long being forced back and forth across the road she was finally able to look around her and admire the sights of where she was instead of simply keeping a paranoid watch for the oncoming traffic she'd dealt with virtually her whole life. No, this time she had a chance to really make a go of things!
Onwards she hopped, between the feet of all the people, avoiding eye contact with anyone she thought might try so make do her famous line one more time (Yeah, fame sucks when you only have two lines, and everyone knows the first half). She looked into the distance and say the horizon for the first time and decided that that was where she needed to go! And so she did.
It was an arduous journey, harder than she'd really expected. Looking to the skies as the geese flew overhead made her ashamed of her own wings, which she would stretch out mournfully each time she saw them soaring above. She never lacked for food at least, as she pecked up any bugs, worms, or stuff that looked like seeds and might even have been. But each morning the horizon looked as far away as the day before, and she started to doubt herself. She would ask any creatures about it, but they had better things to worry about that a stupid chicken trying to traverse the countryside. But no matter her doubts she never faltered, ever pressing onwards.
Then a fox ate her.
