Weapons and Gadgets
- Max and 99 finally become engaged in this episode. However, it has been pointed out that he never actually proposes.
- This episode is a parody of the TV series Mission: Impossible including such tropes of that show as Max receiving his orders via tape recording and selecting the agents from a stack of photographs; among the rejects are entertainer Tiny Tim and Alfred E. Neuman of MADD Magazine!
- On the tape recording, the Chief follows the usual Mission: Impossible warning that "Should you decide to accept this assignment, this department will disavow any knowledge of your actions" with "Should you decide not to accept it...YOU'RE FIRED!"
- Likewise, the self-destruct of the tape backfires, destroying all the lockers...except the one the recorder is in!
