AHAHAHAHA!!!! I had a funny experience just a few minutes
ago....
As you guys may remember, my bachelor's degree was in mechanical
engineering, with a specialization in aeronautical engineering. My
class created our own polo tee just prior to graduation...

Then just as a joke, we put emblazoned the back with the words
'ROCKET SCIENTIST'. (we did learn about rockets, but just a bit
about its propulsion)
:

Then just a few minutes ago in the lift, a girl (most probably a
freshman) stared at the words on my back.
She asked me with a shocked (and really serious) look:
'Wahhh.... Are you really a rocket scientist?!?! How old are
you?!?!?!' 



Lulz ppl actually fall for that
But I think the whole concept is really cute
