i have some things on my hard drive that may have appeared on tv at some point in time, several decades ago. i don't have them on seperate media and i didn't record them off a tv. i'm pretty sure the blake's 7 episode 'city at the edge of time' counts. its not in a form that can be physically touched of course. 15 seconds, i don't know if it would start that quickly, without closing my browser window furst. but then actually finding any of the hundreds of small things i can reach without getting up might actually take closer to 20 or even 45 too. a banana .
