I have a story which predates WordPad, but concerns OLE support in it's predecessor Write:

At my secondary school, a long time ago now, they used PCs from educational vendor Research Machines (RM). These ran a locked down version of the Windows 3.11 Program Manager which didn't allow you to start any unapproved programs. I discovered you could embed EXEs from a floppy disk as OLE objects in a Write document and then start them from within Write by double clicking. In this manner, I could bring my LibertyBasic programs in from home and run them on the school's machines :-).

We also used PCs from RM at our secondary school in the late 2000s. At that time there was still a very similar exploit that allowed me to embed and run unauthorised programs inside of PowerPoint slide shows. Fun times.
