Did the same thing about 12 years ago at a stocked pond near Olds. The little bugger went for my feet the second he got his paws on the bank. I had to sidestep him and he kept coming right at me. I cut half my leader off with my hemostats to get him to stop. Unfortunately he took the fly and half the leader back into the water with him.
Over the years I have also caught a gull, a sparrow, freshwater clams, a playboy magazine, an old jacket. There are probably others but this is all I can recall atm.
