Interesting idea. Whilst I am all for a poster that has something other than the usual A is apple, I do sometimes get frustrated with things that are too politically correct. Whilst I don't expect something to 100% represent my beliefs, family etc, I would have no interest in something that was completely opposite iykwim.

I do like milk for M. Will have to think about D.

Would be so nice to see one that is Australian (not using terms like jelly for jam or cap for hat), but is not completely over the top with Australianisms.
