just remember, tribbles breed so quickly, they're born pregnant. This makes them troublesome; but the trick is to keep their food supply heavily restricted.
FWIW, when i was like... 6 or 7... I was visiting my uncle and found his complete collection of Star Trek on VHS. My dad and bro were off at a soccer tournament, mom, aunt and my uncle were all down stairs talking about boring adult stuff and I just started plopping the tapes in. he walks in on me when I was on Trouble With Tribbles; and says, "OH this is my favorite, Rewind it while I go make some popcorn."...
And then we started binging Star Trek together. (and yes, this might be part of why I'm an incorrigible nerd.) he had through the then-current TNG season.
