SOLUTION: Print up a sign containing only the text "BOOGA BOOGA BOOGA" and the subtext "This sign brought to you by the House Nine Department of Random Signage" and adhere it to the center of the bathroom mirror.
Well, it's a start.
Oh, and because the number of relevant people is increasing: If you've got me listed as a friend, and I don't have you listed, it's not really anything personal- in every present case, it's because I don't know you well enough at all. This situation can be easily and quickly remedied, however: post comments! That's probably the fastest solution.
