Okay, when you're putting strings into a database, you have to delimit them with either double or single quotes. So if you want to actually have a double or single quote character, you have to "escape" them with a backslash so that the database knows you want a quote character within the string, and it's not just the end of the string.
Then, when you get the string out of the database, in PHP you'd call the stripslashes function, which removes all the extra backslashes so everything looks normal. Except for some reason, it's not happening here and we're getting all the messages and comics etc with escape characters intact.
