It is alway fun for me to see what is on a bicycle and heading to market.
It might not be as fun for the pig.
This pig was not in a "poke" so everyone knew exactly what they would get.
He was literally "hog tied". Perhaps he was in deep contemplation about the lyrics he was trying to remember for the ride home. Was it "whee, whee or whee, whee, whee" all the way home?
I am not sure what home he would be going to.
Life on the road must always be about the journey and not the destination.
