I've always liked riddles. I've made this one myself. Try to solve it. The person who makes it can post a new riddle if he/she wants.
Zim and Zam were trying to find out who of them who was the tallest. Despite the height difference between them being 1 foot (30 centimeters) it was impossible for them to find out who the tallest one was. This was not due to lack of intelligence or problems with the landscape. The landscape was flat and they stood next to each other for a long amount of time, and they just couldn't find out how to determine who the tallest of them was. Why was this so hard for them?
