Of course, the thing about the can opener, though, is that's one more thing where from what we see, Jack really isn't as good with it as he thinks he is--or tells Ennis he is (like he says the mare can't throw him, and then she gets lucky--yeah, right, Jack). The only time we actually see Jack use the can opener, what happens? The lid gives way into the can, and Jack gets sauce from the beans all over himself.
Sorry, I guess that's kinda OT here. ...
