Riddle

[spoiler=BAM!]Does Tom Lie? If yes, give it to that robot, if no, give it to the other robot [spoiler=logic] Does tom lie? (let's say he does lie - answer should be yes) yes - from John (would have to say yes in this case because he always tells the truth) no - from Tom (would have to say no in this case because he lies) (let's say he doesn't lie - answer should be no) yes - From john (would have to say yes because he lies) no - from Tom (Tom doesn't lie, has to say no) [/spoiler] Could also flip it with "Does John Lie?" and give it to that robot if no, other robot if yes[/spoiler]

CBT - VERY GOOD!!

Argh! How I haven't thought of that! :S Good job cbt ^^

another one [spoiler] DO YOU EXIST [/spoiler] Give it to the robot who claims existence.

Ok I just made this up, let me know how it goes over. A man fights in world war I, dies at the end of world war 2, and only sees 12 birthdays. What day, month, and year was he born?

[spoiler]29 February 1892?[/spoiler]

[spoiler]29 Feb, 1892?[/spoiler]

That was quick. Psymon got it. Thought for sure the everyone would guess [spoiler]Feb 29, 1900[/spoiler] Edit: Brithday and birthdate are actually distinct entities, so Maafi is correct, not Psymon, still kinda shocked it was answered so fast.

[spoiler]Can't have been 1900[/spoiler]

[spoiler]That was the point Maafi :)[/spoiler]

[spoiler]Still I consider the day I was born a birthday personally. If something happened in 1957 on my birthday, I wouldn't say that happened on the day I was born 44 years early. I would say, he that event happened on my birthday! To me a birthday, is ANY July 11th. Legally speaking though, your first birthday isn't the day you are born, it's the year after on that same day. AKA - you can drink on your 21st birthday. Conventionally, the idiom birthday to me is ANY year ever on the day I was born. So Psymon could be right if he was counting the year the guy is born.[/spoiler] Rephrase: A man fights one world war, dies at the end of another world war, and only sees 11 birthdays not including the day he was born. What day, month, and year was he born?

Beta, your riddle doesn't specify whether the robots know if the other robot is a truth teller or not. [spoiler]If Tom is the liar, the question "Does Tom lie? could be answered "I don't know" by both robots. In that case you still don't know which robot to give the package to.[/spoiler]

Or if the Robots even know each other's names to be more speculative, which AC pointed out even earlier today.

@AC and @CBT true points. I should've specified that they [i]'know all'[/i]

CBT [spoiler]To the rephrase, it would be 29 Feb 1896, right? ( and then you've set up your direct trap for 1900.) Good riddle - need to know dates of wars, think about leap years! and about the gregorian calendar![/spoiler] Also is your birthday [i]really[/i] coming up, or is that just to get the well wishes! :P
