The ambiguous slogan 'Pijpen? Een Euro!' has put De Boekanier on the map among students. 'Pijpen' for which one euro is charged could refer to anything from pipes, narrow glasses or bottles of beer to a blow job. In this case, it's not the latter, so don't expect any oral sex on the menu. The slogan in fact refers to a narrow glass of Jupiler beer which can be purchased for only €1.10 on Thursdays. Other slogans include 'geen kakje zonder zakje' near the toilets (which refers to scooping up dog crap) and 'No Feeding, Please' above the DJ booth.
