Wally explains to Dilbert his theory of everything and Wally reveals to his boss why he can never be fired.
In The Key To Happiness, Wally says, 'I disapoint people, but I'm learning to enjoy it. The key to happiness is to love who you are, not who others want you to be.' Dilbert says, 'Doesn't that make you a sociopath?' Wally says, 'Yeah. I love that about me.'
In Top Performer, Wally says, 'Over the past year most of my coworkers have managed expensive projects that failed. I've done nothing but drink coffee. So on an economic basis, that makes me your top performer. Watch and learn.'
