Who is the bigger fool?

Raghu and Raj were two friends and neighbours. Raghu had a servant named Ramu. The name of Raj’s servant was Shammu. Both servants were foolish. One day the two friends were laughing at the foolishness of their servants. After a while, the two friends debated for hours whose servant was a greater fool. Then they decided to give a test to their servants. The next day they both brought their servants to the park. Raghu told Ramu “Run back to my house to find out if I am there or not”.

Ramu immediately rushed to Raghu's house and Raj told Shammu "Go to your room and find out if you are there or not.” Shammu immediately rushed to Raj's home. After the servants returned, Ramu complained to his master that he had wasted his time and he was not there. Shammu told that his master could have used the phone to call him and ask. Then both friends sighed and they came to the conclusion that only God could decide who was the bigger fool.
