S'okay - after going over all the fabulous names you guys suggested (Winner and Waster! Rosencrantz and Guildenstern!), I've narrowed it down to the two sets of actual twins: Guy and Miles (from Bevis of Hampton), the original Castor and Pollux, and also something that I came up with in my eternal quest to resolve the great enmity 'twixed the Houses: York and Lancaster. But, I put it to TD and asked him to decide. He thought that York and Lancaster sounded like they'd be fighting all the time; ultimately, he likes Guy and Miles because he thinks the names are funny and they're also easier to type (as opposed to, say, Romulus and Remus).
Although you can't expect me to be delivering these guys on my own in the wilderness like Josian did, I like the fact that these twins get along, don't kill one another in a dispute, and have the same father. You can't say that about all medieval/classical twinage.
When they come out, they might be given different handles, but this will do for the next few months!
Thanks guys and have fun at K'zoo!
