Four old cowboys are having a discussion about what is the fastest thing in the world. First cowboy says, I believe it's thinking, cause when you prick your finger or touch a flame, the pain instantly becomes thought and hits the brain. Second cowboy says, Well, I think its blinking. When you blink and open your eyes again, you immediately see everything. Nothing is changed. Third cowboy says, Well, I think it's light, cause as soon as you press that light switch, you go from dark to instant light. Fourth cowboy says, Well, I think it's the Mexican-two-step diarrhoea. All the others ask simultaneously, Diarrhoea? Why? Fourth cowboy says, I'll explain it to you. I went across the border to a saloon last night and drank a buncha home-made Mexican tequila. On the way home from the saloon, I stopped off at Lupe's cafe and ate two helpings of her Mexican Special, which had been warmed over a time or two, and a buncha jalapenas and some chilli peppers I never saw before. First cowboy asks, So, what's that got to do with speed or diarrhoea? Fourth cowboy says, Well, later on when I was in bed, I felt this fire and fierce rumbling in my belly, and before I could think, or blink, or turn that damn light on....
