One hot summer day, a redneck came to town with his dog, tied it under the shade of a tree, and headed into the bar for a cold one.

Twenty minutes later, a policeman entered the bar and asked, 'Who owns the dog tied under that tree outside?'

The redneck said it was his.

'Your dog seems to be in heat' the officer said.

The redneck 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 bred.'

'No way,' said the redneck. 'That dog don't need bread. She ain't hungry 'cause I fed her this mornin'.'

The exasperated policeman said, 'NO! You don't understand; your dog wants to have sex!'

The redneck looked at the cop and said, 'Well, go ahead. I always wanted a police dog.
