[ WP ] A judge tells a condemned prisoner that he will be hanged at noon on one weekday in the following week but that the execution will be a surprise to the prisoner . He will not know the day of the hanging until the executioner knocks on his cell door at noon that day .

Monday: 
 
 It ca n't be today, because he just told me so I'm expecting it. 
 
 Tuesday: 
 
 It ca n't be today, because it's the day after he told me and I'd expect that. 
 
 Wednesday: 
 
 It a definitely not today! I expect them to be trying to scare me, making me think it would be yesterday but it's really today so it must be today so I am expecting it' 
 
 Thurday: 
 
 They're playing a waiting game. 
 
 Friday: 
 
 Hmm. Curious to see what happens if I reach Monday. Pardon? 
 
 Saturday: 
 
 It's got to be today, they would n't leave it last minute but then maybe they would to mess with me. 
 
 Sunday: 
 
 It's 11:59. Am I not going to die? Is this some sort of paradoxical immortality? Is this. 
 
 Knock knock knock 
 
 Shit. I shout'I expected this would happen! Ca n't kill me!' 
 
 A guard enters brandishing a pistol. He says 
 
'Sorry about this, I forgot. Could n't leave you hanging! Bet you did n't expect this' 
 
 Bang.
