A haiku written about the subject of defecating at work. Typically, they are written by programmers and emailed to each other.
The following s'haiku is particularly skillful, following both the 7-5-7 scheme as well as a clever rhyme.

Bagel club groaning. moaning
Do not eat the meat
Cause I need the toilet seat
