'If we're going to get nit-picky about grammar, spelling and such, your last statement should read:

"There are three sports: hunting, shooting and fishing."'

If I was being really nit-picky, I would point out that that should more properly be:

'There are three sports; hunting, shooting, and fishing.' or
'There are three sports: Hunting, shooting, and fishing.'

Unless this example of punctuation has been changed since I was at school, which is probable! I haven't seen speech-marks in a book for ages, for instance, and the serial comma, as you rightly point out, is another thing being abandoned. However, as it more correctly fits my old-world speaking patterns, I refuse to conform to this instance of modern modes. The whole point of punctuation is to enable the reader to 'hear' the writers language.

Of course, I'm not being nit-picky at all, just poking the borax at Mr. Webster's definitions, and using the incorrect word 'proper' to draw attention to that.
Have a nice day, josepp.
