This morning’s name (which just popped into my head; I’m pretty sure I’d never seen or heard it before) was the playful Elrond Hubbard, which has been adopted by a fair number of people on the net — for instance, a fictional character with a Facebook account:
Elrond Hubbard is a renowned science fiction author and prophet. His mother was an elf and his father was an alien from a master race. He claims the face on Mars is of his father.
And in a Twitter account for @Elrond_Hubbard:
By truly believing in Scientology, you too can be an immortal Elf.
