Yeah, yeah :)
I know that:
# grep username /var/log/radius.log
...is much, much better than:
# cat /var/log/radius.log | grep username
...but that is just semantics, relative to the intent and purpose of

Besides, our mail servers don't do enough work, so using cat in the
wrong context when modifying tens of thousands of lines in a file is
good exercise for my boxes ;)
