Okay, this isn't strictly to do with aagragaah, but I thought you might enjoy some more of Detritus the Troll's unique perspective on life. From The Fifth Elephant:
They walked into the hall, and Vimes's eye fell on a pile of cards on a table by the door.
'Der's been a lot of visitors,' said Detritus.
Vimes took a handful of cards. Some of them had gold edging.
'Dem diplomatics all want you to come for drinky-poos an' stories about chickens,' the troll added helpfully.
'Cocktails, I think you'll find,' said Vimes, reading through the pasteboards.
