My flatmate is not a Transformer

Eariler today, my flatmate (yet to be Bud Light) was testing himself. No algebra or biology was involved. He would have failed if there was. Instead of a scholastic test, he performed tests following the scientific approach. He had an idea, created a hypothesis, tested the hypothesis using variables, and finally reformulated using hypothesis. All tests proved contrary to his hypothesis. The final conclusion reached was that he is not a Tranformer with the alternate form of a train. Even yelling "choo choo" rather loud did not activate any form of Transformer power.
