Sales Geek: "We have to have (PROJECT A) done by Friday. Make this your top priority."
Programmers: "What about (PROJECT B)?"
Sales Geek: "Oh yeah... that one needs to be done by Friday... top priority."
Programmers: "Well there's absolutely NO way we're going to have BOTH done by Friday? Which do you want done first?"
Sales Geek: "Uh... BOTH."
Programmers: "Nonononono... you don't understand... You have a choice of ONE of these two being done... -A- or -B-. Which one do you want done by Friday?"
Sales Geek: "I told you... I want BOTH!"
Neither of them got done.
