Just for fun, how many Klingon words/phrases I can recall off the top of my head:
Qa'pla, racht, gagh, bat'leth, mek'leth, pe'taQ, d'k tahg, Hab SoslI' Quch, rokeg, gre'thor, sto-vo-kor, targ, raktajino, cha'dich, grishnar, chech'tluth. So I can guess I can basically order food, insult someone, or name a weapon (and I'm pretty sure the spelling or capitalization is off on half those words.)
Does anyone actually speak Klingon? Seriously?
