The theorem has been expressed colloquially as "you can't comb a hairy ball flat without creating a cowlick" or "you can't comb the hair on a coconut".

How else do you do it? Cookies? JavaScript? That would be terrible.

Responsive design usually doesn't require detecting anything about the client. There's probably some differences in actual HTML markup between mobile/non-mobile Wikipedia, but I'd be surprised if it has to be that way. Media queries have been available for a long, long time.
