Not sure if Ted is Canadian, but it's a joke.

Mention the letters to CRTC to any Canadian and that's what they think about.

The letters CRTC are in some of the function calls.

[grapeshot → howeyc]

It's for CRT Controller (probably after the Motorola 6845 CRTC chip that was in the original PC)

[gpvos → grapeshot]

Well, maybe the documentation for the function could have mentioned that. Oh no, there was none.

[wnoise → grapeshot]

And CRT is short for Cathode Ray Tube.
