Upon the ' s arrival at the planet Motherlode , Captain Kirk asks Spock what the odds are of Harry Mudd ' s presence on the planet . Spock tells the captain that the odds of him being on the surface are approximately eighty - one percent , plus or minus . 53 . " " Why can ' t you just say " Mudd ' s probably there ? " , " " Dr . McCoy asks . " " I just did , doctor , " " Spock replies . Lieutenant Arex reports that the " Enterprise " has entered parking orbit of the planet . Kirk beams down to Motherlode with Spock , and after locating Mudd , Kirk tells him that he ' s wanted for fraud , illegal drug manufacturing and swindling . For proof Mudd demonstrates the potion on a woman who Spock discovers to actually be a reptilian illusion created by a Rigelian hypnoid . Angered by this , the miner s begin to attack Mudd , but he is once again rescued by the " Enterprise " crew , apprehended and incarcerated . Aboard the ship , Spock requests a medical report from Nurse Chapel . Mudd , imprisioned in the brig , sees that she is enamored of him but he is " a trifle lacking in the warmer emotions . " He then proceeds to convince Chapel to try the potion on Spock . When Chapel thinks that the potion doesn ' t actually work , she becomes bitter and seeks out Mudd . Without warning , the potion begins to take an effect on Spock . He wasn ' t immune to it , it just took a little longer for a Vulcan , and as he hands over his report with her summary appended he says , " " Ahh . Nurse Chapel ' s sweet summary . Dear , lovely , Christine . " " During a fight between Mudd and Chapel , love crystals are broken near an air vent in the " Enterprise " s shuttlebay and permeate throughout the ship . It begins to affect the entire crew . Mudd captures Chapel and escapes to a rocky planet in a stolen shuttlecraft . The love - stricken Spock becomes so enamored with his beloved Nurse Chapel that he will do anything to rescue her . Spock wants to lead a landing party and he tells Kirk , " " Captain , I insist upon going . Christine , I can ' t stand the thought of any danger to her . The woman I love . " " Kirk exclaims , " " Love , Spock ? " " Spock replies , " " Yes , captain . I want to protect her . Hold her in my arms . " " Spock seems to be utterly unstoppable . Spock says , " " Come on , hurry . If he ' s harmed one hair on her pretty head . . . " " Kirk accompanies Spock but they are attacked on the planet by rock beast s . Spock asks Chapel , " " Darling . Are you all right ? " " Chapel questions , " " Darling ? How wonderful . " " Unable to transport to the vessel because of the potion ' s affect on the crew , Kirk asks Spock , " " Can ' t you take your hands off her ? " " Spock replies , " " That ' s my affair . Jim . No , captain . We ' re both reacting to the drug . The love potion . " " On the ship in sickbay , McCoy is flirting with a crew woman and says , " " Did I ever tell you about the time I saved Captain Kirk ' s life ? Or Spock ' s ? And my dear friend Scotty ? And that pretty little Lieutenant Uhura . I ' ve saved just about everybody on this here ship . If the " Enterprise " had a heart , I ' d save her too . Oh , let ' s talk about your heart , my dear . " " When Kirk thinks he can distract the beasts Spock tells him , " " That is an outstandingly stupid idea ! Ah , I ' m sorry . The drug . I simply doubt that we can appeal to their better nature , if they have one . " " Kirk , though , uses the crystals to make the beasts become docile and loving . Eventually the potion wears off and the crew beams everyone back to the ship , but then the potions after effects cause hatred and animosity among the crew . Mudd is placed back in the brig , where he confesses to other con jobs . When Spock then asks Chapel if he can help her to record Harry Mudd ' s confession , she adamantly repulses him . Spock comments , " " A few moments of love paid for with several hours of hatred . Your potion is scarcely a bargain , Harry . " " Spock then assures Mudd he will get rehabilitation therapy for his crimes . Mudd laughingly answers , " " I just hate to leave you all , all my loved ones . " " Memorable quotes . " " The probability of his presence on Motherlode is eight - one percent , plus or minus . 53 . " " " " Why can ' t you just say , ' Mudd ' s probably there ? " " " " I just did , Doctor . " " " " They ' ll find you soon enough my little poppet . You ' ll be safe and I ' ll be long gone . " " " " Gone where ? The planet ' s a desert . " " " " There ' s always a market for an ingenious man . " " " " Captain , Doctor . . . I . . . uh , wish to report a number of strange . . . emotions . " " " " What ? " " " " What ? " " " " You ' re funny and very attractive for a Human . " " " " By the way , anybody keeping a trace on the captain and Mr . Spock ? " " " " Sure , Arex . " " " " Thanks , Jim , it ' s good to have a friend like you . " " " " Strange , that ' s how I feel about you , too . My dear friend Spock . " " " " Jim . No , captain . We ' re both reacting to the drug . The love potion . " " ( Surprised ) " " It worked ? " " " " I ' ve saved just about everybody on this here ship .
