I just remembered something I did a while back to try to make it a bit less boring for the folks when installing your CPAN module (Acme::EyeDrops in this example). I organised the test names so that they deliver a haiku as you run make test:

t/00_Coffee.........ok
t/01_mug............ok
t/02_shatters.......ok
t/03_Larry..........ok
t/04_Apocalyptic....ok
t/05_Parrot.........ok
t/06_not............ok
t/07_a..............ok
t/08_hoax...........ok
t/09_Gallop.........ok
t/10_Ponie..........ok
t/11_bold...........ok
t/12_Beer...........ok
t/13_to.............ok
t/14_gulp...........ok
t/15_Buffy..........ok
t/16_astride........ok
t/17_Orange.........ok
t/18_sky............ok
t/19_surrounds......ok

The haiku above was derived from A brief history of Perl 6 development in haiku. Not especially noteworthy perhaps, though I don't know of anyone else who has tried this. Perhaps others have livened up their CPAN module installs in other ways.
