Fail videos are so ubiquitous that one can usually predict the outcome based upon the setting and props involved. Ramp/pond/bike, guy on roof/folding table on ground, skateboard/stairs, skateboard/park bench/handrail, skateboard/steep hill, merry-go-round/motorcycle, large group of people posing for picture/dock/platform/stage, rope swing/lake, rally car/rally, idiot(s)/fire, idiot(s)/fireworks, concert/stage diver, cat/slippery counter, dog/slippery floor, pickup truck/guy riding something attached to pickup by a rope, park/parkourer parkourering, motorcycle/ramp, motorcycle/wheelie, poser/posing with animal, person buried in sand/dog, inattentive jogger/signpost, ridiculously expensive luxury car/just drivin' down the road, car/trolley, car/bus, car/train gate, car/other traffic control devices, singer/national anthem... etc.

I still like watching them, though. The misfortune of others can be very entertaining (as long as no one gets seriously hurt).
