1500 !

This is my 1500th consecutive Blip so I reverted to one of my favourite subjects - my 'Gang of Four'. Sometimes they are the subject because of what they have been doing that day but quite often it is a case of 'it's almost midnight and no Blip today - I'll have to shoot a dog!'
How do I get them to sit so well? in a word - bribery - a doggy biccy in my hand does the trick every time !
