One of the robbers accidentaly drops his mask. He puts it back, but he knows it is too late.
So he asks the closest man: ‘Did you see anything?’
‘Well, yes, I was close and…’
The robber shoots him instantly. He then goes to the second closest: ‘What did you see?’
‘Nothing!’ says the man, frightened. ‘But my wife doesn’t miss anything…’
‘Where’s your wife!’ the robber yells. ‘Show her to me!’
‘She’s at home, but I can call her and she’ll be here in five minutes.’
