One day on the set of ST:TNG, during the time that Patrick Stewart was also doing voice-overs for Pontiac advertisements, he had the entire crew rolling in the aisles after he walked in fully dressed as Locutus of Borg, opened his mouth, and said, "Have you considered buying a Pontiac?". I think that relates to this comic. I've forgotten how. Must have been a rough night.
[edit, in response to e-mails] No, no, Star Trek: The Next Generation, not STagic: The New Gathering. I don't even think you're being serious.
