http://en.wikipedia.org/wiki/Married_and_maiden_names#Children
This wikipedia page posits a scenario in which a woman named Jane Dice and a man named John Klax have a child, to whom they give the surname Dilax. A review of the history page reveals that until December 7, 2009, the page put forth the slightly more reasonable but still unlikely story of Jane Peak and John Dixon and their child, surnamed Peaxon. There is nothing on the discussion page to explain the change. For that matter, there is no sourcing of the very statement that people are combining their last names into crazy shit. One can only imagine what linguistic abomination would be birthed if John Dilax had a child with Jane Peaxon. Dilaxon? Peaxax? Pildealxqwryuuuuk?
I like to imagine that this is why aliens and people from the future in science fiction have ridiculous, unnatural names. They’re just into very progressive marriages.
