Artisanal Bubble Gum
My initial thought was Glee Gum...I don't know if I would call it artisanal, but it's the most funky gum I could think of that's easy to find. They also sell a kit where you can make your own gum...so maybe your husband could become the funky bubble gum maker?
This site sells a lot of novelty gums, including bacon gumballs?: http://www.perpetualkid.com/bacon-gum...
This one has unsual nostalgic gums, which you could probably also find at Vermont Country store now that I think about it: http://www.victoryseeds.com/candystor...
