Many frustrating arguments against fellow Australians on the pronunciation of the word 'ass'. It is not pronounced 'arse', for that is a completely separate word with a different meaning. This is only really an issue with words like jackass, smart-ass etc. being pronounced as 'jack-arse', 'smart-arse', which aren't real words, and mean nothing. Of course, this is countered by "durr, get out of here American, we pronounce it differently because we're Australian." NO! You're saying it wrong! AAAAAAHHHH!
Also, on the subject of Batman: I'm hearing a lot of arguments to the tune of "Villains like the Joker only exist because of Batman. If Batman didn't exist, there'd be no villains in Gotham." Um, what? So, by that logic, if we got rid of the Fire Department, there'd be no fires? If we get rid of hospitals, nobody will get sick?
