Caffeine addiction - up to eleven

Not much time for blogging these days but I'll share a weird moment that happened in class today:
Prof notices that it's one hour into the lecture and announces that we'll take a 15-minute break after the next three slides.
One slide later a student's hand goes up.
"Mr Z, can we take the break now after all?"
"Two more slides. Why, do you have to go now?"
The student looks at him apologetically and says: "I wanted to go get some coffee."
Well, at least he was honest...
