 The ice skating scenes were shot in an actual rink . According to Jenna Fischer , Steve Carell used to play hockey , and the writers had been looking for a reason to use Carell 's ice skating skills in an episode . Fischer had also learned to skate in preparation for the movie Blades of Glory , but the writers decided that there was no reason for Pam to be a good skater , so they had Pam lean on Jim . Saturday Night Live alumna Nancy Walls , who played Carol Stills , is actually Steve Carell 's wife . At the rink , Michael tells Pam to be wary of breast cancer . This is the third joke that Stupnitsky and Eisenberg had aimed at Pam 's breasts , after one each in " The Fight " and " The Secret " . Fischer later jokingly said that " my breasts play a central role in one of tonight 's scenes . " Fischer also noted that , due to the slight emphasis her breasts were receiving , many fans on the internet were arguing that Fischer had had breast implants . Fischer denied the rumors , but stated that she was " flattered " .
