Bill and Derek are out walking their dogs -- Bill has a German shepherd, while Derek is trailing a Chihuahua. They've been out for a while and Bill suggests stopping in at Starbucks for some coffee.

"We can't go in there with the dogs," replies Derek.

"Sure we can," says Bill. "Just follow my lead."

Bill puts on his sunglasses and walks into Starbucks. A cop stops him and says, "Sir, you can't bring a dog in here."

"This is my seeing-eye dog," says Bill, and the cop lets him in.

Derek watches this exchange, shrugs and puts on his sunglasses. The same cop meets him as soon as he gets in the door. "Sir, you can't bring a dog in here."

"This is my seeing-eye dog," says Derek.

Skeptically, the cop says, "Your seeing-eye dog is a Chihuahua?"

"They gave me a CHIHUAHUA?!?!?!"
