A PROMISING NEW OBESITY DRUG: If it works, the market will be huge.
Emphasis mine.
Was that pun on purpose, or not? At first, I didn’t think so, but the more times I read it, the more I think it was. If he had italicized the pun like I did, it would have been obvious…
UPDATE: After thinking about it, if it works, the market won’t be huge: it will be millions of pounds lighter, in aggregate. No?
