Counter Example

An ambitious young graduate student gave a surprise lecture where he claimed to have disproven the Riemann Hypothesis. He began by drawing the Cayley Tables for some interesting groups. He used a table of integrals and a table of Laplace transforms to demonstrate some identities. Then he wrote up some complicated truth tables to wade through some convoluted hypotheses. Finally he wrapped it all up with an appeal to the periodic table of elements. "You idiot!!" his mentor shouted from the audience. "That's not a counter example... it's a table example!!!"
