About 15 years ago I was bank-fishing at Blue
Creek on the Cowlitz. It was late summer and the river was pretty low. A driftboat comes down the middle of the river with two passengers, one of which is standing on a seat or something in the back of the boat. The boat bumps a rock pretty hard lifting the guy in the boat 8-10 inches into the air, but when he came down the boat had floated past him leaving him standing in the middle of the river. Amazing that he landed on his feet and didn't slip or fall. About 30 yards down river his buddies realize he's gone and look back to see him hollering and waving! Lucky for him the guy on the stix was pretty strong and rowed back up the riffle and picked him up again STILL DRY!
I wouldn't have believed it if I hadn't watched the whole thing.
