This sentence on my Google front page managed to confuse me until I read the corresponding article:

Ban cements lead in UN race

A couple of the weirder improbable interpretations going through my head at the time:

• Certain glues are banned - and attain a favourable ranking - in an UN motorsport event?
• Glue containing heavy metal is banned in an UN motorsport event?
• Heavy metal is firmly established in an UN motorsport event due to some ban?

Need to stop here, head spinning. Having a closer look at the sentence, there's only two words (in and UN) that aren't ambiguous enough to confuse.
