What would you want your plant to sniff out?

Apparently our tax dollars are hard at work developing plants that can sniff out bombs!! It appears they can “program” these plants to sniff out other chemicals like radon to TNT! I can see a quite a few everyday applications with this technology and I ask my fellow Jellies if they would line up to get a plant that could sniff out what at home? What role could a blood hound household plant be in your home?

Sniff out lost remotes and keys? Detect whether your 9 year actually took a bath like they say they did? What could this plant sniff out that would make your life easier or safer??
