An Old man has a bad tooth ache, he goes into the dentist office. The dentist brings him into the room and looks at the tooth, he tells the old man we cant fix it we need to pull it out! The dentist gets some novacane, the old man says I canÃ¢â‚¬â„¢t take that…I am allergic to it! So the dentist leaves the room and comes back with some laughing gas…the old man says I canÃ¢â‚¬â„¢t take that I am allergic to it! So the dentist is getting mad, leaves the room and comes back and sticks two pills in the old mans hand and says take these! The old man takes the pills and asks what were they? The dentist tells him it was Viagara! The old mans says Viagara??? the dentist says sure is…you are going to need something to hold onto while I pull your tooth out!
