I frequently use cat to splice standard input into a sequence of files.
Here's a question I once put to a bunch of students I was teaching:

"If I have the following in /etc/crontab:

05 06 * * 5 root /usr/bin/find /usr /bin /sbin -type f -perm +4000 | cat \
        /root/suid.orig /root/suid.orig - | sort | uniq -u


Then
        a) What am I doing?
        b) How does it work?
        c) Why is /root/suid.orig named twice?"

It is impolite to tell a man who is carrying you on his shoulders that
his head smells.
