A man with a doberman and his friend, who owns a chihuahua, are going for a walk. After a while they get hungry and the man with the doberman says to his friend: "lets grab a bite to eat in that restuarant over there" The man with the chihuahua replies " I don't think they'll let us in with our dogs." -- "Don't worry about it" the guy with the doberman says. He puts on a pair of sunglasses and hands a pair to his friend. Then he tries to walk into the restaurant, but the doorman says " sorry, no pets allowed" The man with the doberman says "You don't understand, this is my seeing eye dog!" --- " a doberman?" the doorman asks.--- "yes" the man replies" they're using them now, they are quick learners. I wouldn't know what to do without my Rufus." The doorman nods understandingly and lets the man and his dog pass. a few minutes later the man with the chihuahua walks over to the restaurant. again the doorman says " no pets allowed!" The man replies " I am blind and this is my seeing eye dog."--- "a chihuahua?" the doorman wonders. The man looks surprised and says " you mean they gave me a chihuahua?"
