Looking at the photo - you can get what the gist is all about. The guy is a very big nose picking enthusiast, and he trained his pet parrot to help out. There is no other logical explanation why would anyone do something like this, and there is no way parrots could have evolved the instinct to pick a mammal's nose. There is no way that can be true.
To be honest, there is an even better explanation about this. The guy's mother someone else had complained to him about his nose picking, which is why he had to stop. But he had an idea - he could leave little crumbs in his nose so that the parrot would get trained to pick them up. That way he would have plausible deniability when his mom talked against nose picking.
