Reminds me of an old sketch that goes like this:
Late nineties, the guy A is sitting on a park bench. Suddenly his friend B approaches and shows A his cool new watch that can do a lot of cool tricks (like voice assistant, weather etc - so a staple for modern smartwatches). A is amazed and eventually convinces his friend to give the watch to him. As A is about to run away, B stops him, telling that A forgot the batteries and points out at two large (and obviously heavy) suitecases B was lugging around.
