It’s Knot Easy
Get it? It’s a joke. A pun. Knot easy is a pun. A pun is just like a joke, only not funny. Knot funny, if you will.
Do you know who never used puns? Men who gnu how to tie knots. I mean, knew how to tie knots. Sailors who did more than enter regattas. Painters, carpenters, and window washers who needed to set up rigging for planks when hanging off the side of tall structures. Believe you me, if your life depended on the quality of your knots, you’d learn more than the “tie your shoes” knot.
