Wally says to the Boss, "I was so motivated by your pep talk yesterday that I came to work ten minutes early!" The Boss replies, "Wally, we start at eight, not at nine." Wally responds, "That's gonna cost you ten minutes."
Boss: I'm getting a lot of complaints about you being late for meetings. Wally: They never talk about anything important in the first ten minutes. Boss: They're usually talking about you being late. Wally: Why would I need to be there for that?
