This line/scene came to mind recently, it is not fully fleshed as a "joke" but I hope you find it funny.
Scene. Person walks into a sporting goods shop and is looking through the knife display. Asks to see a knife, handles it and the customers service person asks, "How does it feel?"
The customer responds, "The action is so "Canadian" I can't reach into my pocket to pay, so it's got to go away. Thanks."
Or, Person walks into a sporting goods shop. While looking at the display, a customer service person asks, "Is there any thing you would like to see."
The person replies, "Yes, that X knife, as long as the action is not "Canadian.""
For me, it is one of those things.... Like what else can you do but laugh? The reality is silly and some what futile but I can still get the knives I like. Also, embracing it in a way eases the tension. I am sure there is a better joke out there about knives that require 2 hands to open.
Please feel free to share your stories/jokes of knives with "Canadian Opening Action." Not about the politics, about the knives, please.
