Hello, I believe you need to take another look at my contribution to the "I'm With Stupid" page, as it doesn't really explain a joke by any means. The edit was implying that when SpongeBob says "Hey, a note!", there's a blank side to the paper (visible to the screen), but the letter was suddenly there when he showed that same side later. Though, I do believe that the joke kind of ruins its substance if the letter was shown before.
Oh, sorry. It wasn't a bot. You're just having Wikia automatically update the file links whenever you move the episode images. If you don't want to rename the files without updating, I would suggest doing it with a bot or not doing so many all at once.
Second, please do not say "thank you" before someone does something because if I had said, "I will not do that.". you would have looks embarrassed that you said, "Thank you" before hand. In other words, you should only say, "Thank you" after someone has done what you have asked them.
