Two guys are outside a bar with their dogs when the first guy says, "Let's go in and have a drink".

The second guy says, "You know they won't let us in with our dogs."

The first guy says, "Just do what I do and we'll get in".

The first guy puts on sunglasses and starts into the bar. The bouncer sees him and yells out "Hey buddy, no pets allowed in this bar!".

The first guy replies, "Sir, I am blind and this is my seeing eye dog."

The bouncer, feeling really bad, says "Oh, I'm really sorry. Go on in and have a seat."

The second guy puts on sunglasses and goes into the bar. The bouncer sees him and shouts out, "No dogs allowed in here."

The second guy replies, "I'm blind and this is my seeing eye dog."

The bouncer says, "Give me a break! Your dog is a Chihauhua!" to which second guy repies, "What! You mean they gave me a Chihauhua!?"
