**Warning ** off topic but one of the most inovative uses of degrees I've heard.
On ground at LHR a few years back, Non-english speaking airline pilot verses the LHR Ground controller:
Ground: "XXX push approved, face west"
Pilot: " push approved say again direction"
Ground: "Face west"
Pilot: "say again"
Ground "Face west"
Pilot "say again direction"
Ground " sigh.....push approved...............face 270 degrees...."
Pilot " Ah, OK push appoved face west"
Well it made us smile......
