There has been a discussion in the comment section of Watts Up With That about the use of tow vs toe in the phrase “Toe the line”. It means not exceeding bounds or limits.
A commenter there said:

Aaagh! I can’t stand it any longer! The phrase is “toeing the line” i.e. “not stepping over the line” not ‘towing the line.” Nobody is pulling a line or rope anywhere – and even if such a phrase existed, it would not make sense in the context of the complaints here, that the mainstream media is failing to move forward with investigative journalism. Maxx is not the only one who uses the wrong word.

I dunno. I’m up on toe vs tow and I think it makes perfect sense.
Line = official position. As in “The current Communist Party Line on Global warming….”
So towing the line would mean supporting the official position through heavy labor. As in “haul on the bowline, we sang that melody….” (those of you of a “certain age” will get the reference).
