I once got into a conversation at a high school party when one person was talking about the theory of evolution and how it was supported by the fossil record.
NOTE: This person was not actually discussing it, he was using it as a metaphor for something else.
I come back by explaining how the term of 'theory' differs in a scientific context and that the fossil record was just one avenue of an immense amount of things built around evolution. These included nuclear haplotype sequence homology, affixiation, speciation, abiogenesis (which is technically not part of evolution), extinction, population regulation and adaptation were just some of the many others worth mentioning.
I look up and realise that everyone is staring at me with the kind of:
"Why the hell is he talking about this?"
Look and I realised I had managed to effectivley bore the entire table. So in other words I was well and truly my father's son.
EDIT: Also I once made an essay for an exam which featured dozens of non sequiter referances to Aliens and Terminator movies.
