Thanks for the feedback as always everybody. This stuff is very much work in progress and I was trying to develop a couple of characters. I don't think the first sketch was ever intended to be shocking as such, as humans eat quite a lot of duck, it was just meant to be mildly amusing/very slightly surprising. I think the second one moves it on a bit as babies are off the menu for most of us and I agree that the third is more or less like the second in terms of impact. There is a very much darker version of the third sketch but I'm not happy to post it at the mo. Work in progress!
As for the first one being written by a 10 year old, Dave that's OK by me as they laugh too and might like it! Also it's good to look through a childs eyes from time to time I reckon. As it's handy to take a squint through the eyes of a bitter and twisted old git occasionally (as you well know!)
Arf! Arf!
