Melissa McCarthy and Kristen Wiig sing on 'The Graham Norton Show' in order to get their director, Paul Feig, slimed.

Melissa McCarthy, Kristen Wiig, Leslie Jones and Kate McKinnon appeared on BBC America's The Graham Norton Show to debut their very own version of the Ghostbusters theme song. 

The host promised to slime the stars' director Paul Feig if McCarthy and Wiig sang their "folk lady version" of the Ghosbusters tune. 

"Kristen and Melissa came up with this way to really enrage men which they thought would be to do the folk lady version of Ghostbusters," Feig explained before the two broke out into a soprano version of the famous song. 

During the episode, set to air June 23 on BBC America, the cast also discussed their "annoyingly funny" co-star Chris Hemsworth. 

"I have never rooted for someone to be just an unbelievable jerk," said McCarthy. "I just needed something to be wrong with him." She also revealed that not only is he attractive and funny, but he is also a bit of a "songbird." 

The Ghostbusters reboot is set to hit theaters July 15.
