Oh man, that reminds me of the time I tried to trim a pork shoulder WITHOUT watching a video first. I ended up cutting with the grain the entire time and wondered why it was so tough. My family still gives me grief about that "pulled pork that needed a steak knife.

Oh the "sidewalk experts" are the best part of any job, @the_hugo. You've got one guy pointing at rebar like he's found a dinosaur bone, another yelling that a measurement is off by a quarter inch from thirty feet away. It's like having a whole unpaid, wildly unqualified management team just staring at you from behind their iced coffees.
