Here's another funny comment i once read. This one was on a puzzle that involved Queening a pawn. It said:
"Mouse slip. Who would ever promote to a Bishop?"

It seems that the chess.com people have finally corrected the most common complaint about Tactics Trainer.
It used to be that if you got the correct solution but were too slow you lost points. I didn't read any offical announcement that it has been corrected, but when i plaay now if I take a long time and still get the correct solution, I get +1 point. 
That is a big deal to me.

Here's another funny comment from someone else I read after a TT problem.
This problem consists of nothing more than knowledge that a bishop can move backwards. Regretably, it took me more than 3 minutes to remember how a bishop moves. At times like this, I consider giving up chess altogether.
As I mentioned, I play a lot of TT problems, probably average about 20 a day. I often comment after the problem and read other comments. Because I have been doing this so long, I recognize about 6 or 8 others who also play a lot and comment a lot. We are a TT community talking to each other in a sorta random way.
I see a few comments that really stand out. One was from a guy that I don't know, but his comment was great. He saw the solution and said, "Not nearly as good as my elaborate plan to win a pawn".
Yea that's a good one!
