Hi all,

An easter-egg in the version of man that is installed on the most popular Linux distros has recently been discovered after being there for 6 years:

https://unix.stackexchange.com/questions/405783/why-does-man-print-gimme-gimme-gimme-at-0030

It is for example discussed here:

It makes man print 'gimme gimme gimme' if called at "Half past twelve", as in the ABBA song.

I check on BSD, but man seems to be a shell script on FreeBSD, so it's immune from the easter egg:

Do you have any UNIX easter-egg stories ? Putting some in, or discovering one...

Was this kind of humor tolerated in the professional settings where UNIX first circulated, or was it frowned upon ?
