When two of the three are grinning you had better hold on to your billfold and keep your back to the wall.
When all three are grinning it's too late - your billfold is already gone and the knife is in your back.

Notice that Nana Piglosi is missing from the celebration.
She has become so toxic that even a bottom-feeding paste-eater like Schmucky Schumer doesn't want to be photographed with her.
Good one.
