Guide Dogs
Two men are walking doberman and a chihuahua when they see a restaurant.
They're pretty hungry, so they decide to head in for a bite to eat. Unfortunately, they see a sign out front that says "NO DOGS ALLOWED".
The man with the doberman says "I know what to do, just follow my lead." He throws on a pair of sunglasses and walks in.
The waiter tells him "I'm sorry sir, we don't allow dogs here." The man says "Oh, you don't understand. I'm blind and this is my guide dog."
"A doberman for a guide dog?" The waiter asks, skeptical.
"Yes." The man replies. "Dobermans are very loyal. They're easy to train and protective too. They're born for the job."
The waiter sighs and leads the man to a table.
The second man, excited by this idea, throws on his sunglasses and walks in.
The waiter tells him "I'm sorry sir, we don't allow dogs here." The man says "Oh, you don't understand. I'm blind and this is my guide dog."
"A chihuahua for a guide dog?" The waiter asks.
"A chihuahua?" The man asks. "They gave me a chihuahua?!?"
