I think my worst was doing some clearance pruning from a house a year ago in an oak. Everything went so damn smooth, I was feeling so confident and good. Set line fast, fun limb walks, great rigging by my ground guy and finished way sooner than I anticipated. Go to pull my line out once on the ground and it falls into another crotch and the freaking spliced eye got impossibly stuck. No matter how hard we pulled it didn’t come out, and probably got worse. Groundie ended up getting the big extension latter, which still wasn’t big enough and using a pole clip and more struggling it finally came out.
