No really Morrowind better Skyrim. But don't have Morrowind in my steam library. Anyone "Thanks for Morrowind"?

You are more awesome than a monkey wearing a tuxedo made out of bacon riding a cyborg unicorn with a light saber for the horn riding on the tip of a space shuttle closing in on Mars while engulfed in flames.

Thank you for Skyrim.

I sense a public lynching here giggles
Let me get my scythe!

I don't know who started it, but presumably it grew out of the period where there were so many secret puzzle threads that you could barely tell which threads had puzzles and which didn't. So in order to troll / make people paranoid one would thank for games on many threads.

Also, thanks for Skyrim!

Haha, very clever! Thanks for Skyrim :D

if rly i think it wasnt a joke someone just said real thanks for skyrim on secrete giveaway topic and all was mad on him and then all started to do that on all other puzle topic :<

Thanks for useless thread !

You say fail joke, I say TROLOLOLOLO

Thanks for Fortix!

It would be nice to see more like... original jokes.... like this:

I'm in the urge to show my appreciation to your persona for giving myself an opportunity to participate in the lottery that was ingeniously hidden in your sharp commentary, lottery that I must add is for a role exchanging video entertainment that takes place in a kingdom with the name of Skyrim that it's the same name of the aforementioned pixelated entertainment that is very much appreciated by the chaps fanatic to said entertainment, computational program that can only be accessed though the service proportioned by the gentlemen working at the Valve Corporation, name that has been taken by this community of nice and exquisite chaps and chapettes and that with the addition of the word gifts, pointing out that this fraternity is aimed to charity for helping those in need of electronic entertainment.

Just like you my dear gentleman are doing with myself.

Who wants to go back through every forum/giveaway and check? (not me)
