Bind Energy Puns

A little context: I'm driving around in Yellowstone with my dad and my girlfriend. My dad went on a three week cross country ski winter camping trip when he was 17 in Yellowstone. We are currently talking about whether or not it is important to carry bear spray.

Dad: "Did I ever tell you about that time I woke up a bear on my ski trip?"

Me: "What?! No, that's crazy, what happened?"

Dad: "Well, we were skiing through an open field when we hear a rumbling from about 100 yards behind us, and we turn back and there's a huge bear, and he looks at us and starts lumbering in our direction. At the time, I was with this girl who was not a very good skier, but we were pretty sure black bears can't climb trees, so we start hustling towards the woods. So I'm pulling her along and this bear is gaining on us but we get to the closest climbable tree and the bear is still 50 yards back. Like I said, she wasn't a very good skier, or really very coordinated in general, so I help boost her up into the tree and she's up there and she's pretty safe, but this took a minute and a lot of my energy. So now the bear is only about 15 feet away, and I've still got my skis on, and, you know, back then we didn't have fancy cross country skis, we had these big metal cable bindings and leather lace up boots, so I definitely don't have time to get them off. And I'm so exhausted from dragging this girl across the field and then shoving her up into the tree that I've got almost nothing left, and the first branch is about 8 feet off the ground. But this bear is coming at me and there's nothing I can do but jump for it, so I leap and pull myself up and over the branch using everything I've got right as the bear lunges for me and bites into my ski boot. So here I am, doubled over this branch with a bear's jaws on my foot, my skis on, and not one ounce of energy left, and he's really sinking his teeth in and he's really just pulling my leg just like I'm pulling yours!"
