Why do programmers drink so much coffee?

(You get that cup of coffee, feel that delicious smell, drink the perfect combination of flavor and caffeine, and feel you'll have a perfect day!)
Programmer: Hmmmm...
(But then you remember you're a programmer...)
Programmer: Crap!
(So you get another cup of coffee, feel that delicious smell, drink the perfect combination of flavor and caffeine, and feel you'll have a perfect day!)
Programmer: Hmmmm...
(Now you're in a infinite loop...)
