One hot summer day
A blonde came to town with her dog, tied it under the shade of a tree and headed into a restaurant for something cold to drink. Twenty minutes later, a policeman entered the restaurant and asked: "Who owns the dog tied under that tree outside? "
The blonde said it was hers.
"Your dog seems to be in heat, " the officer said.
The blonde replied: "No way. She's cool 'cause she's tied up under that tree. "
The policeman said: "No, you don't understand. Your dog needs to be bred. "
"No way," said the blonde: "My dog doesn't need bread. She isn't hungry 'cause I fed her this morning. "
The exasperated policeman said: "You still don't understand. Your dog wants to have sex!"
The blonde looked at the cop and said: "Well, go ahead. I always wanted a police dog."
