The Tuners and Technicians forum over at Pianoworld.com can get pretty heated, even though most of the regulars there are sensible, down to earth types who are helpful with all the mechanical stuff about pianos. Even on a boring day, the thread titles are funny, but maybe that is just my twisted little mind. You decide, here are a few from the first page this morning:

Bobbling When Hard Blow
Prout's and Chris Leslie's Beaters
Overpull, then ?

The funny Craigslist listings are always entertaining too.
