Surprise and embarrassment is funny to me. Surprise of course is a key to comedy. Embarrassment because often it is temporary pain which is easier to laugh at and with.
Things that have changed is often somehow funny to me. Any advancement (tech or otherwise) that can cause confusion is ripe for a laugh.
New things that you have acquired can cause for some pain or special effort to understand or learn. A new car, new hi-tech TV system, new computer, new watch etc etc....something that you bought to improve your life can get off to slow start doing so and so to me is fertile ground for funny.
