Melissa McCarthy's impressions of White House Press Secretary Sean Spicer have been one of the highlights of SNL this year. 

Which is why NBC knows that a promo focused entirely around McCarthy transforming into Spicer is going to be a hit with fans. 

Dancing through the studio to the tune of 'I Feel Pretty' from West Side Story, McCarthy quickly finds herself in the make up chair to begin the makeover process. 

McCarthy is going to be guest hosting this weekend's episode and she'll have plenty of material to work with following the dismissal of former FBI Director James Comey mid week. 

Speaking of James Comey, Chris Pratt had the best possible response to the news of his dismissal on Twitter.
