Pretending to Be Blind

There were these two guys, walking their dog's, one was a Doberman and one was a Chihuahua. As they were walking, they passed a bar and wanted to get in. But there was a sign in the window that said: NO PETS ALLOWED! So the guy with the Doberman said, "Let's go in as blind men with seeing-eye dog's!" They agreed that the guy with the Doberman would go in first.
The first guy told the guard that the Doberman was his seeing-eye dog, so he got in. When the second guy tried to get in, the guard said "Exuse me sir but, Chihuahuas aren't seeing-eye dogs!" 
The guy say's "THEY GAVE ME A CHIHUAHUA?!!"
