Today I was at the dentist ... He needed to do a circular x-ray to see how much jaw bone was left after the accident of ten years ago, as he needs to do further surgery. I told his nurse I hated x-rays!
Hmmmm.... so the x-ray came back blank. I told the dentist "that is because I am an Alien".
So he sent me back again and tried a second time and again the x-ray came back blank. Dentist said, "there is absolutely no radiation at all coming from that machine. It appears to be broken." I laughed and apologized for breaking his machine, as "we have been neutralizing the radiation on the planet." My joke left him really wondering about me, "Yes I do believe you are an alien."
