One of my fishing buddies was absolutely terrible at tying knots. I must have shown him how to tie a Palomar knot 15 times. Most of the time I ended up tying on his baits. Well when I was busy he was on his own. On at least 3 separate occasions I witnessed him tie a knot, proceed to trim what he thought was the tag end then toss his bait off the side of the boat as he picked up his rod as he watched his bait sink and his line blow in the wind. Luckily one of these times was a hollow body frog so he could scoop it back up. plus there's all the baits I've seen go sailing a mile due to his poor knots.
