I personally enjoy real life real time watching people walk into fountains and planters along a street. Seen that numerous times. Maybe I can be a jerk at times but when I see someone walking towards me or even close by and have taken many steps without looking up, when they're close enough I shout loudly "LOOK OUT". The startled jumped reaction is precious.
Only have a few got mad at me but I just walk away. Too many times over the years I've done it for real to save their bodies and face.
