I don't think funny and offensive are mutually exclusive.
There are plenty of jokes, racist, sexist, those that do the rounds after a natural disaster, which might raise a titter. They're still offensive though.
Dog's joke seemed fairly tame to me. One of our teachers around 3rd year of Grammer school marched into a stuffy classroom and threw windows open complaining that 'it smells like a Turkish brothel in here'.
The class wag, with admirable speed, asked 'how do you know what a Turkish brothel smells like Sir?'
collapse of entire class (or at least those who knew what a brothel was).
