Congress: We demand that you say 2+2 = 5. Oh, and in metric — no, English – no, wait Metric — tonnes.
NASA: Uh… What?
Congress: Well, we just passed a law that says you must say that 2+2=5 metric-English tonnes. You have one month to get back to us.
One month later…
Congress: Stop lying! You have another six months to think this over and come to the correct answer.
Six months later…
NASA: Well, we found that “2+2…+1 = 5 metric-English tonnes.” But, we’re having another guy look at it, to be sure.
Congress: Stop lying! Subpoena!
I imagine that the teddy bears (or dogs, or whatever they are) will have something to say about this soon.
