Tell us a joke?

Two guys are waiting at a crosswalk. One of them asks the other, "Are you a fireman?" The other guy seems surprised and says, "That's an odd question, but yes, I am." Intrigued, the first guy asks if he can see his fire gear. The fireman agrees and takes him to the nearby fire station. He shows him the usual stuff – hoses, gear, etc. When they get to the fire truck, the first guy asks, "Why doesn't your fire truck have an engine?" The fireman replies, "Oh, it burned out." The guy notices a cat where the engine should be and asks, "Why is there a cat there?" The fireman explains, "Since we don't have an engine, the cat is there instead." Baffled, the guy asks, "But why is the cat tied to the firetruck?" The fireman responds, "That's because it pulls the truck. We don't have an engine, remember?" Still puzzled, the guy asks, "Okay, but why is it attached by the foot?" The fireman says, "Let me show you." He pulls a cord attached to the cat's foot, and the cat screeches, "Weeow, weeow, weeow!"
