I give you a group of three. One is sitting down, and will never get up. The second eats as much as is given to him, yet is always hungry. The third goes away and never returns. What are the three things?
"Great Job You Got It"
This riddle is named after Julius Caesar, who is thought to be first to use this cipher.
Simply count the letters and arrange them in groups of the same number, here 4 will be easiest. It will be make 4 rows of 4. Then you put the rows one above the other and read up down, like so:
G T Y O
R J O T
E O U I
A B G T
Until you find the message.
