In essence much the same as the Spiderman
but you pull out at the last moment and pop a neatly painted Warhammer 40K miniature in her mouth.
This is traditionally done from behind, but works equally well from in front but it can be trickier to hide the miniatures.
Beginners can use plastic miniatures and progress up to leaded ones but they must always be painted.
I dry brushed Diane last night and she was probably only expecting a plastic gene stealer.
