I've had some fun ones, when interviewing folks - back in the days when people where hiring.
* had someone make a giant cheat sheet with interview questions and taped it to the wall behind their computer. Part way through, the tape gave out and covered him.
* had someone attempt to lip sync the answers. The guy talking and the guy on screen were not the same guy. There was a bit of pretend 'oh just lag' for a while.
* Person we interviewed was not the same one who showed up for work. Great answers, great experience on the interview. Asked about some things we had talked about for quite a while - and he could not recall anything. Came to realize not the same person.
* the glorious mechanical keyboard furiously googling for an answer.
* the sample project they were asked to create as starting point for the interview, they had never run before. They sat and read through what was likely AI generated docs to run the app. Took them a while to realize they needed something other than Java 8 installed to run the sample.
