being from Denmark, and not having seen older Us tv-shows, movies etc. that may be required viewing for every American, I sometimes have trouble "getting" references in movies (usually spoofs/comedys). And I was hoping someone could tell me where the lines originally appeared, so here goes :
"Today is a good day to die" , (Worf says it in TNG a lot)
"I got no where else to go" (Chris Farley, Wayne's World 2)
(In brackets are the movies I saw the phrases in)
Homer: There's your giraffe, little girl. Ralph: I'm a boy! Homer: That's the spirit. Never give up.
What was the question again? I think the question you are asking is MIB guys and the DJ the same? If so, then the answer is no. The DJ is just a normal guy like the mailman. They are just there to move the plot along.
