If TT had more time/resources, it would be genuinely great to have a bonus spoof ending a la the legendary dog ending of Silent Hill 2.
(For those of you who don't know, the intensely serious horror game Silent Hill 2 contained a joke ending that could only be obtained on a second playthrough, in which it is revealed that a dog pulling levers at a console has been controlling all the games events.)

If Walking Dead S1 were to do something similar, I would go for Kenny and Lee leaping into each others arms and revealing their real feelings for each other as they rub moustaches. Would probably be more upsettling than all the zombie violence in many ways.
