A bloke went to the dentist and found he'd have to have a tooth extracted. The dentist prepared to give him an injection but he refused, saying he hated needles. She offered him a mouthwash to deaden the area but he didn't like the taste and refused. Eventually, she asked him if he could handle tablets. When he said yes, she gave him two. He had taken one before he actually looked at the other and asked, 'Why are you giving me Viagra?' The dentist replied, ' So you'll have something to hold onto when I pull your tooth!'
