Likewise - it's only happened a few times in my life, but there have been moments in a 2k-line long SQL stored proc I inherited that I needed to print the thing off and user markers to try group code up and figure out what was happening (it was a monstrosity with no formatting or comments lol)

But yeah day to day, even year to year nobody is printing off their code to look at it - let alone only 20 lines of it lol
