This is really a great one
Three convicts escaped from prison. One was a Madrasi, one a Gujarati, and one a Sardar. They ran for miles until they came upon an old barn where they decided to hide in the hayloft and rest. When they climbed up, they found three large gunnysacks and decided to climb into them for camouflage.
About an hour later the Prison Warden and his assistant came into the barn. The warden told his assistant to go up and check out the hayloft. When he got up there the warden asked him what he saw and the assistant yelled back, "Just three gunnysacks."
The warden told him to find out what was in them, so the assistant kicked the first sack, which had the Madrasi in it. He went, "Bow-wow", so the assistant told the warden there was a dog in it. Then he kicked the sack with the Gujarati in it. He went, "Meow", so the assistant told the warden there was a cat in it. Then he kicked the one with the Sardar in it, and there was no sound at all. So he kicked it again, and finally the Sardar said, "Potatoes".
