There's a story of a company that was selling a box to connect to your TV that'd take the closed captioning signal, and on detecting "vulgar" or "offensive" language, it'd bleep out the sound and replace the captions with something less offensive.

The jokes about Dick Van Dyke's name are very old (but usually they use Penis Van Lesbian), so it was quite likely just a variant used by the company itself as a PR sound-bite to get people to write about them. It seems like it worked - it appeared in quite a lot of news stories and some are still online:
