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 shade 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, ‘NO! You 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.‘
