Are ya bein' funny at my expense? 

 OK, but wild animals will become frustrated, bite (as hapenned here) and it is usually they who pay the price.  Every time a bear is fed and becomes habituated to humans, it loses its life.  Maybe if we started shooting humans, the feeding would stop.

I think in Mary Poppins the kids bought bird seed and fed it - which is quite different than low nutrition and gummy bread which has nutrients birds cannot process.

Note the girls white dress - did the sea lion think someone was holding out on giving him more bread?
