strange thieves

I work at a garden store during the summer, and today one of my projects was to organize and "clean" the vinca. These flowers are in plastic containers that are divided into six sections, with a plant in each section. The reason why I have to do this: customers sometimes pull plants out and either throw them aside or steal them. And then the boss and I got into a storytelling-session on stupid/weird thieves.

Me: I didn't realize we had so many crazy people this year!
Boss: Yeah, I have no idea where they're coming from. They're stealing plants like there's no tomorrow. Look at this. (holds up two plastic pots still half-full of dirt) There used to be hostas in these. Who the heck steals a plant that's going to grow into a bush? What did they do, stick the plant into their pocket?!?! At least in this one they left the tags saying which plant it is. They took the tag out of the other one!
Me: I haven't even seen these thieves.
Boss: The other day, Jerry [her son who also works there] saw this man who had all the trays of begonias laid out on the floor and was pulling plants out and reorganizing them because the plants weren't all exactly the same size. Jerry told him to "get the hell out."

This prompted me to think of other stupid criminals.

Anybody have stories or stupid or odd thieves to share?
