Correction Conundrum
Oops, wait – is the grammar in the third panel correct? Worst case scenario I might have to travel back in time to correct any mistakes.
Oh, and the second panel is a bit of an homage to Kris Straub’s “Time Friends” comic. I couldn’t find it hosted online anymore, but I found a couple examples on Google image search.
Third panel grammar looks good to me. Did you mean the “zero humans” part? That’s correct as per https://ell.stackexchange.com/a/115010.
Jeez did some AI write that third panel or something??
Well, it wasn’t a human, since there weren’t any to write it.
So either AI or a cat that’s better than average at typing.
Unfortunately for everyone, the first mistake they fix is the invention of time-travel.
