today i made an astounding discovery. not everyone understand my jokes!
for example, i said 'live long and prosper' to my coursemate today as i bid him goodbye after lecture 1 (yes, accompanied by the famous handsign). he laughed.
afterwards, when we meet again for lecture 2, i asked him: haven't seen you in a hundred years, how's it going since the blackholetrip? and he laughed politely.
throughout lecture, i was thinking of something to continue on with that startrek joke and i came up with this to say to him at the end of lecture: ah do you prefer chris pine or spock?
and he said: who are they?
me: hm.. star trek?
him: oh. isnt that the movie with the laser swords?
me: ... that's star wars dude. and it's call LIGHT SABERS
him: oh. star wars and star trek. ah.. there's a difference?

the point is not his ignorance, but the fact that....

WHAT WERE YOU THNINKING WHEN I SAID SILLY THINGS LIKE: live long and prosper instead of a common earthling goodbye?!!??
