I've been to many, but two stick out in my mind. There was a team-building workshop that was mandatory for my department after we went through a period of civil unrest.* That workshop was memorable because we learned that you can beat someone with a phone book and it won't leave telltale bruises.
Another was a workshop where we learned about validation and saw a short film on validation. That one stuck with me because I love the guy in it. You. Are. Awesome!
And you are. TOAD-ALLY AWESOME!
Now stand back and give me some phone book swinging room.
The Fine Print: * Civil unrest = a bunch of adults forgot this wasn't junior high and no one really cares who likes who or who is having lunch with who and who didn't get invited to prom. No, really, just do your effing job. Stamp credits holy crap I forgot to check. Stamps by some stamp company. How's that for a save?
