Also possibly because I ran out of time to write a real post:
A PuG’s an iffy, frightful thing at best,
Scarce worth the effort that it takes to run,
The drooling savage beats upon his breast,
And into pieces shatters all your fun.
“Link the metres!” cry the horrid beasties,
Frothing to see if they top o’erall.
Woe to those who issue stern entreaties,
To stop with all the fucking “gogolawl”.
Perhaps you wonder: why join at such cost?
‘Cause PuG or not – I want my Goddammned Frost.
