Yes, I know they do - I was quite suprised the first time I saw workmates posting piccies of it on facebook. I do wonder what the point is - yes, it's funny, but if you want a messy child to laugh at give them paint, or mud, or the left over bowl of frosting. Also, in NZ at least, it's very disrespectful to ruin and play with food like that (it's a Maori culture thing, but totally relevant still today given how many people are living under the poverty line) so I also wonder how Maori feel about it.
