Went to add 25#s to my deadlift bar today and someone had overloaded the peg the weights were on so it wasn't on the peg all the way. Touched it and it fell on my toe.
Ouch! I had a boss that had similar... got under the bar to bench press and wham! Right on his forehead. Off to the hospital for stitches.
Why do things fall? Gravity overcomes surface tension.
