This stamp by London-based designer Dominic Wilcox, formerly of Mosley Meets Wilcox, pretty much says it all for me. I can't even walk into a Bath & Body Works without having a seizure from all the fruity smells, especially during the holidays, ick. Get the above honesty stamp here ($24) and check out some others in the series, like "You're right, the key to a strong relationship is communication." here ($29).
*Above stamp reads: "No socks, underpants or smelly soap will be accepted this Christmas"
