Here is a nice short Tron reference from german television.
On a channel for children television there is a show featuring "Bernd the Brot" and his friends. Bernd is grumpy most of the time and wants to be left alone. But his friends, a overexcited sheep that loves stunts and a living shrubbery that makes explosive inventions, won't let him be.
When the program is over in the evening a nightloop starts. This loop(s) always consist of Bernd being unabel to leave the screen. When he walks out left; he comes back in on the right , when he digs through the floor he falls from the ceiling etc.
In this loop he competes against the Weißbox-Master-Control-Programm. And in the end he ends up on the game grid. Unfortunately the loop ends here and starts from the beginning. Maybe it wil go on in another loop in the future

I made a simple transript of the dialog before the Tron sequence:
Bernd: "What have I got to do to stop this?"
WMCP: You would have to find ME, the Weißbox(whitebox)-Master-Control-Programm, and switch me off"
Bernd: "Then I will do this!"
WMCP: "You can try...bread!"
*digitize beam*
WMCP: "Welcome in my world user. Give up all your hopes whuahahha!"
Bernd: "The most dangerous enemies are these who don't need hope anymore "
