From the “Sic!” section of World Wide Words #731 (5/9/11):
Aoife Bairead saw a headline in the Sunday Business Post of Ireland dated 3 April: “Bishops agree sex abuse rules”.
The crucial bit of syntax — “transitivizing P-drop” (see here) for ‘agree on/to’ — is widespread in British and Irish English, but it can result in risible ambiguities, specifically when what follows agree can be understood as an object clause, as it can here, thanks to the existence of both a noun rule (what was intended in the headline) and a verb rule and to the existence of both a transitive and an intransitive verb rule. All these factors combine to yield a possible, but unwanted, interpretation ‘agree that sex abuse rules’: a fine crash blossom (see here).
