I went to the travel agent the other day for some advice on a holiday and told him I am afraid of flying because there might be a bomb on the plane. He told me the chances of a bomb being on a plane are over a million to one. I told him it was still too big a risk for me. He advised me to take a bomb of my own. When I asked, “what the hell for?” he told me that the chances of two bombs being on the same plane are twenty million to one!
