Thanks for your answer.
How do I find that -20 comment? Outliers can be ignored but at the risk of not learning something new.
This is the page of your comments. I got to it by clicking on your username, then clicking comments at the top. Unfortunately, the comments can only be sorted chronologically with the most recent first unless you use something like WeiDai's tool, which can be sorted (but apparently only in descending order, and it doesn't seem to have the -20 comment).
Since you have so few comments, it's relatively easy to look at them all and find it here.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
