A guy and his blonde girlfriend are driving to the movies one night for a date. As the guy was making a right turn, he noticed his turn signal light inside the car didn't light up at all.

So as he approached the next right turn, he asked his girlfriend to please stick her head out the window and tell him if his turn signal is working. She happily obliges and at the turn she sticks her head out the window and replies, "It is... It isn't... It is... It isn't... It is... It isn't."
