One time when I was in college I saw a guy be approached by someone who was collecting for charity "for MS". He must have been missing a context cue, in addition to being a huge nerd, because he said he didn't support MS -- thinking, probably, that MS meant "Microsoft" and not "multiple sclerosis".

I recall this anecdote now because of the inherent poetry: the essence of this treatment is to treat the immune system like a corrupted Windows installation -- wipe and reinstall from scratch.
