    Puzzle 6
    Answer: 120, 240

    Puzzle 8
    Answer: 2, 7

    Puzzle 10
    Answer: 6, 14

    Puzzle 11 made me scramble but I came up with 'no solution' also.

    Again, well done!

    Good job RYou!. I am not sure 2 can be the correct solution to Puzzle 11 because 2 is not a square number, (is it?) The square root of 2 is an irrational number so therefore 2 is not a square (Pythagoras's constant). At least that's my thinking. What is your rationale?

    My number is less than 200.
    My number is even.

    I don't think 75 is an even number!
    I will smash your face into a car windshield and then take your mother, Dorothy Mantooth, out to a nice seafood dinner and never call her again!

    Tell me about it, this morning, I woke up and I shit a squirrel, but what I can't get is the damn thing is still alive. So now, I've got a shit covered squirrel running around my office and I don't know what to name it.
