One of the cuttings a team member on Radio 4's comedy show The News Quiz earlier had brought in for the final round was from the English version of the German magazine Der Spiegel (this is it). It reads:
Too many police, they say, can't read or write, can't shoot straight or take bribes.
I notice I am behind the blogosphere on this one, as many other bloggers published the article days ago and it generated great debate. Some commentators felt that the addition of an Oxford comma would have prevented the amusing ambiguity (as the sentence stands the 'can't' governs 'take bribes' as well as 'shoot straight'). Personally, I don't think the addition of a comma would have been much help. I think the solution would have been to change the word order, insert another 'they', or repeat 'too many', eg
Too many police, they say, take bribes, can't read or write and can't shoot straight (an Oxford comma would have been okay here, but it wouldn't have changed the meaning; moreover, 'and' sounds better to me than the original 'or' here)
or
Too many police, they say, can't read or write, can't shoot straight, or they take bribes.
or
Too many police, they say, can't read or write, can't shoot straight, and too many (of them) take bribes.
