"... like fishing with grenades." I do not recommend this practice. Firstly, it's pretty hard to fry the catch when it is difficult to find the catch. Secondly, you can get very wet. Lastly, it is frowned upon by some authorities, such as the OPP (Ontario Provincial Police). They also frown on fishing with a Sten machine pistol... well, they did back in the '60s when my old man was stationed at CFB Trenton.
Oh, here's a tip if you are thinking about fishing with grenades. Drop your grenades off a concrete deck bridge. Wooden bridges are to be avoided in this endeavour. Well, that's what Dad use to tell me.
