yeah, Brown Bags at our place too.
To be honest, most of them are pretty kick ass. Especially the tech ones. We seem to have a load of kick ass technicians.
Plus given how vast the whole area i work in is - theres always huge sections of the system you couldn't possibly know about so getting a 1 hr overview at least lets you piece it all together and means you start asking the right questions and stop looking a plumb in "real" meetings.
One woman did do one that dealt with treating your dog for depression though. Those sort of brown bags aren't so interesting.(a) If your dog is depressed, you're doing something wrong. If your dog is actually, really, physiologically depressed (which I somehow kind of doubt) then it needs meds or to be put down, so you can start over with a dog that's not broken. :P
