Where can I find jokes like this? (may offend some people)

My grandfather is the nicest guy in the world but he loves 2-5 sentence jokes and jokes that are a little edgy some examples are. Why do girls get their periods? Because they deserve it. How come when women get married they wear white? Because it matches all kitchen appliances. What happened when the guy had an affair with a house keeper? She kept the house. Also the joke im sure everyone is aware off about the lamp 'I wish I was with my friends' And another one is that joke where the husband misses his wifes funeral to go to the superbowl. ​ My grandfather is really old and id like to tell him some new jokes, does anyone have any ideas?
