Two friends, John and Mark, were walking through the forest when they stumbled upon a magical frog. The frog looked at them and said, "Thank you for freeing me from this spell. I will grant each of you one wish."
John wished for a lifetime supply of chocolate. Poof! A mountain of chocolate appeared before him.
Mark thought for a moment and said, "I wish I had a bridge that could connect us to the neighboring village." Poof! A beautiful bridge appeared over a nearby river.
They both thanked the frog and went on their way. A few weeks later, they met again. John was enjoying his chocolate, but Mark seemed troubled.
John asked, "What's wrong, Mark? You got your bridge, didn't you?"
Mark sighed and replied, "Yes, I did, but the villagers named it 'Mark's Bridge,' and now they want me to pay tolls every time I cross it!"
