Santa and his two friends are talking at a bar. His first friend says, "I think my wife is having an affair with the electrician. The other day I came home and found wire cutters under our bed and they weren't mine." His second friend says, "I think my wife is having an affair with the plumber, the other day I found a wrench under the bed and it wasn't mine." Santa says, "I think my wife is having an affair with a horse." Both his friends look at him with utter disbelief. "No I'm serious. The other day I came home and found a jockey under our bed." ********************** A surd wants to somehow get a doctorate. One of his friend advises him to do research in zoology. So the surd decides to do his research in zoology, that too with a Frog. He first keeps the frog on a table and asks it to jump. It jumps. Now he cuts one of its legs and keeps it over the table. Again he asks it to jump. Again frog jumps. Getting boosted by this development, now he cuts another leg and asks the frog to jump. The frog jumps again. Getting wondered about it, now he cuts the third leg and again asks it to jump. The rog jumps. Now he could not control the suspense and cuts the fourth leg and ask the frog to jump. It doesn't. Immediately the surd writes in his thesis "If you cut all the four legs of a frog, it will become deaf."
