This one is NOT for the kids or the workplace but is a GREAT video for so many different reasons. Picked this link up from Freddy Camacho's One World blog. Check it out:

What needs to be understood is that beneath the bravado, the swearing, and the verbal beatdowns is that this guy loves his job. He likes the people that go train with him for more than the reason that they are easy cannon-fodder for his wit... and he LOVES his fellow co-workers.
Lesson #1 - find your passion and pursue it
Lesson #2 - surround yourself with good people
That's a pretty damn good start!
