The Duck Giveaway 2016, Seasonal Edition

Friends, the contest is over! The winning number was 50, picked by CarLaTeX. Thanks everybody for joining the contest!

'ello, ladies and gentlemen, boys and girls, ducks and mallards, children of all ages! It is time for organizing another amazing community lottery, our beloved duck giveaway 2016, seasonal edition! The previous giveaway was a huge success, so let us try that again! Quack!

The prize

The prize will be a lovely duck! Not a real one, I am afraid (note to self: organize another lottery with real ducks in the future), it will be a hand puppet duck:

Quack!

Lovely, isn't it?

Again, why a duck? Why not a lion?

As I mentioned in the thread linked here, I always like to provide examples with ducks when I write answers. To my surprise, the theme got a very positive feedback from the community and it spread to everybody. Of course, a lion would be better, but hey, it's free! And it's a duck! :)

Why a hand puppet?

This will be our third lottery offering a duck puppet and I still have absolutely no idea. But since I got this duck again, I thought it would be a good idea to start a contest! :)

Rules

Rules from last lottery still apply:

  • To win the duck you must guess a number in the range 1-200. The first person who guesses the right number gets the duck.

  • Contestants may submit 2 valid guesses. UPDATE: Let us spice things up! you can now select a third entry! :)

  • Please post your guess as an answer to this meta question, not as a comment.

  • Contestants must have been a member of TeX.sx before 1 November, 2016.

Two additional mentions:

  • If two or more people choose the same number, only the oldest entry will be considered. The other guesses will be automatically disqualified.

  • If you win the contest, I will need your real name and address for shipping and customs purposes (you can contact me through email, so only I will have privileged access). If you seek anonymity, we advise you to not enter this contest.

Please don't forget to edit the punch card with your numbers.


The lottery

As seen in the last lottery, I'll use the following code to pick the winner (special thanks to the awesome LaTeX Project for LaTeX3):

\documentclass{article}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\usepackage{expl3}
\usepackage{xparse}

\usepackage{pgf}
\pgfmathsetseed{\number\pdfrandomseed}

\ExplSyntaxOn

\bool_set_false:N \l_duck_contest_winner_bool
\tl_new:N \l_duck_contest_winner_tl
\int_new:N \l_duck_contest_winning_number_int

\NewDocumentCommand { \person } { m m }
{
    \clist_map_inline:nn { #1 }
    {
        \prop_if_in:NnTF \g_duck_contest_prop { ##1 }
        {
            Hey! ~ #2 ~ wants ~ to ~ be ~ naughty! ~
            The ~ number ~ ##1 ~ was ~ already ~ chosen! \par
        }
        {
            \prop_gput:Nnn \g_duck_contest_prop { ##1 } { #2 }
            \int_gset:Nn \g_duck_contest_upper_limit_int
            {
                \int_max:nn { \g_duck_contest_upper_limit_int } { ##1 }
            }
        }
    }
}

\NewDocumentCommand{ \winner } { }
{
    \bool_do_until:Nn \l_duck_contest_winner_bool
    {
        \pgfmathrandom{1, \g_duck_contest_upper_limit_int}
        \prop_get:NoN \g_duck_contest_prop { \pgfmathresult } \l_duck_contest_winner_tl
        \quark_if_no_value:NF \l_duck_contest_winner_tl
        {
            \bool_set_true:N \l_duck_contest_winner_bool
        }
    }
    \int_set_eq:NN \l_duck_contest_winning_number_int \pgfmathresult
    \l_duck_contest_winner_tl
}

\cs_generate_variant:Nn \prop_get:NnN { No }

\NewDocumentCommand{ \winningnumber } { }
{
    \int_to_arabic:n \l_duck_contest_winning_number_int
}

\ExplSyntaxOff

\begin{document}

% add yourself here
% ==============================
% For example, in the following line
% I picked 1 and 27, but I'm not
% participating in the contest :)
% \person{1,27}{Paulo Cereda}
% ==============================

% the announcement
The winner is \winner, with \winningnumber! Congratulations!

\end{document}

I will run this code with all the contestants, post a video of it and announce the winner. The "accepted answer" in this thread will reflect the winning number.

The date

Hopefully, I will get the code running on December 30, 2016 (Friday), and announce the winner. There will be enough time for guessing the numbers!

Good luck! And by the way, welcome to TeX.sx, the friendliest and most awesome community in the whole StackExchange network! They give us hats, right? We give ducks! Quack! :)

    Aside: We are working on a proper random number function for expl3. Bruno's hopefully going to add something soon (and I'm going to bother the XeTeX people for a couple of primitives) – Joseph Wright Nov 9 '16 at 9:14

    @GustavoMezzetti But witches have cats! Ducks are great, but I'm not sure about putting one on the back of my broomstick ... But it is like trying to choose between cake and biscuits. Can't we have both?! – cfr Dec 3 '16 at 3:43

And the third number is 108: the central free in the central verse.
