Given that this card is a Connection and Unique, we can infer that it refers to a single character. So, with that in mind, is this:

(a) A person named Dean Lister
(b) A person who is a dean, with the surname Lister
(c) A person named Dean who makes lists
(d) A person who makes lists of deans
(e) A person who makes lists of people named Dean
(f) A dean who makes lists
(g) A person who makes the Dean's List
Or, most likely,
(h) All of the above

But it's so simple. All I have to do is divine from what I know of you: are you the sort of man who would spend zero, or one credit?

Now, a clever man would spend nothing, because he would know that only a great fool would reach for what he was given. I am not a great fool, so I can clearly not choose zero.

But you must have known I was not a great fool, you would have counted on it, so I can clearly not choose one credit.

Because your credits come from Account Siphon, as everyone knows, and Account Siphon is intended to be played with criminals, and criminals are used to having people not trust them, as you are not trusted by me, so I can clearly not choose zero credits.

You've beaten my Lotus Field, which means you're exceptionally strong, so you could've spent no credits, trusting on your strength to save you, so I can clearly not choose zero credits.

But, you've also bested my Caprice, which means you must have studied, and in studying you must have learned that man is mortal, so you would have put the credits as far from yourself as possible, so I can clearly not pick one credit.

IT HAS WORKED! YOU'VE GIVEN EVERYTHING AWAY! I KNOW WHAT YOU'VE SPENT!

You only think I guessed wrong! That's what's so funny! I chose two credits when your back was turned!

Ha ha! You fool! You fell victim to one of the classic blunders - The most famous of which is "never get involved in a land war in Asia" - but only slightly less well-known is this:

"Never go in against Jinteki when death is on the line"!

Ha ha ha ha ha ha ha! Ha ha ha ha ha ha ha! Ha ha ha... Keels over
