* Basically the whole damn episode.
** William Shatner's clearly having so much fun acting like Kirk acting like an old-time gangster, including at one point when he calls the Enterprise:
--->'''Kirk:''' Hello Scotty, dis is Koik.
** Leonard Nimoy eventually joins in as well.
--->'''Spock''' I would advise youse ta keep dialin', Oxmyx.
** Fizzbin. Just... Fizzbin.[[note]]Did anybody write the rules down...?[[/note]]
** Kirk's attempt at driving a car. Doubly so with Spock's line [[DeadpanSnarker about how he's a great starship captain, but no taxi driver]].
*** Becomes HilariousInHindsight with [[Film/StarTrek2009 the 2009 movie]] showing Kirk driving a car at age 8.
** Spock and Bones have a fun little scene together when they take over a radio station, as [=McCoy=] snarks "helpfully" while Spock figures things out.
* Scotty tries his hand at using gangster slang to intimidate a captured Krako, only for Krako to correct his error in mild annoyance.
-->'''Scotty:''' You mind your place, mister, or you'll be wearing concrete galoshes.\\
'''Krako:''' You mean "cement overshoes"?\\
'''Scotty:''' Er, aye.
