From the you've got to be kidding category:

In his demonstration at the convention, Shalev left the audience amazed
by actually hacking a computer with a toaster.

He said that any home device could be connected with a software prototype to hack a computer. "I read a senior scientist from Google saying there was no need to be afraid of a toaster at home," Shalev told The Indian Express. "But as a hacker I came up with a toaster that could actually hack a computer. I call it a 'Crazy Toaster'."
