Batman’s Greatest Boner —
A series of scans has appeared on the scans_daily LiveJournal blog, apparently from an early Batman comic (Batman #66). It details a 'boner' made by the Joker, and his subsequent efforts to force Batman 'into a boner'. The word boner is repeated so often that it seems like it has to be a joke, especially when you read lines such as
"Gotham City will rue the day it mentioned the word Boner!" Perhaps someone photoshopped the word 'boner' into an issue of Batman. But I don't think so. I think it's real, although I can't be sure since I don't have a copy of that particular Batman comic (in fact, I don't have any Batman comics). The cover of that issue can be
seen here. It's titled 'The Joker's Comedy of Errors!' So the issue itself is real, and 'boner' can mean an error. I think that it's only in recent decades that boner has come to predominantly refer to something else.
Another thing... in one of the panels a newspaper headline reads
"Wrong-Way Batman! Lawman Aims For California, Winds Up In England!" This is a reference to
Wrong-Way Corrigan, an aviator who wanted to fly solo from New York to Dublin but wasn't given permission to do so. So on July 17, 1938 he took off for California and 'accidentally' went the wrong-way and ended up in Ireland.
