Three hungry vampire bats are hanging upside down in a tall tower at night, having not eaten anything for several days. Extremely hungry they look around for something they can drink the blood off.
The first bat, sees something, flies away and returns several minutes later with blood dropping from his cheeks.
The other bats ask him what he set his teeth in and the first bat replies: “Do you see that small bush over there? Well, I saw a rat running towards it and I got to it.”
The other bats now excited start looking around for something they can sink their teeth in and the second bat now takes a dive and returns several minutes later with his whole mouth covered with blood.
The 2 other bats are amazed and ask him what he found. “Well”, says the second bat, “see that red pick up truck over there? It reminded me of a farm nearby which has some cows, so I went there and took a bite.”
The third bat, growing impatiently now starts flying off with great speed and returns several minutes later with his whole face dripping with blood.
The 2 other bats ask him what he found and he says: “Well, see that small post over there?” The other bats nods. “Well” he says, “I didn’t.”
