An old lady in a care home is riding in her electric wheelchair up and down her corridor. All of a sudden, an old man leaps out of his room and says to her, "Madam, you were speeding. May I see your driving licence, please?"

She rummages in her handbag, finds a sweet wrapper and hands it to him.

He examines it and says to her, "Well, just a warning this time..."

The next day she's riding up and down again. He leaps out of his room and says, "Madam, you were driving without due care. May I see your licence, please?"

After another rummage she finds an old receipt and hands it to him.

"Very well, I'll let you off this time but please take more care..."

The next day she's doing the same thing. This time he leaps out of his room stark naked with a huge erection.

"Oh no," she exclaimed, "Not the bloody breathalyser again..."
