In addition to having a horrible memory, I also have a tendency to phrase things incredibly poorly. (Which, if you've read my writing before, isn't a shocker). Consequently, I've had a long history of completely blowing the whole "Do you have any questions" part of the job interview.
Instead of just writing out the questions on a piece of loose leaf or in a bullet list in a Word doc, I took a few extra minutes to make a themed Word doc with headings, questions, and space for notes.
In addition to having a copy of the questions and not making my usual mistakes, I looked organized, prepared, engaged, and like I wasn't lying when I said I knew how to use Microsoft Word. (The person interviewing me even complemented me on it.)
