Secret Santa help..

Does anyone have any good ideas for a Secret Santa gift that is a maximum of $5? This would be for a man. I /could/ see how much individual Lucky Bamboo shoots are and get a cheap container at the dollar store but that would kinda give away who the present is from as I'm the only person in the office with a Lucky Bamboo plant on my desk. He did mention liking the plant, though, so...what do you guys think?
