It's so funny I spit my coffee all over the keyboard. . . . . . . . . Actually ... I lied. Don't bother. They just want you to click on the links endlessly.
The funny thing is that the more it gets reposted the longer the chain gets. I'm guessing that it cuts off into a loop at the end. It's mildly interesting for how the nature of the internet shapes the joke.
A few days ago I was having some work done at my local garage.. A blonde came in and asked for a seven-hundred-ten. We all looked at each other and another customer asked, "What is a seven-hundred-ten?" She replied, "You know, the little piece in the middle of the engine, I have lost it and need a new one.." She replied that she did not know exactly what it was, but this piece had always been there. The mechanic gave her a piece of paper and a pen and asked her to draw what the piece looked like. She drew a circle and in the middle of it wrote 710. He then took her over to another car which had its hood up and asked "is there a 710 on this car?" She pointed and said, "Of course, its right there." If you're not sure what a 710 is Spoiler
I'll throw in a stupid little joke: Why did the chicken commit suicide? Spoiler Because he only got laid once and it was by his mother.
