Leslie Jones Impersonates Will Ferrell in 'SNL' Promo

Leslie Jones demonstrated her readiness for Saturday Night Live veteran Will Ferrell to return to the stage once again in the new promo for his upcoming hosting gig on this week's SNL.

in the promo, Jones celebrates the three-time host's return by impersonating Ferrell's famous SNL characters. Donning a succession of Ferrell's costumes, Jones offers her take on Spartan cheerleader, dancing Roxbury guy, Frank Henderson yelling "Get off the shed!" and his impersonations of Harry Caray, Alex Trebek and George W. Bush. 

Jones finishes her round of impersonations with Ferrell's popular Blue Oyster Cult cowbell player. As Jones tries to live up to the "more cowbell" mandate, Ferrell becomes visibly annoyed. 

Ferrell is set to host SNL on Jan. 27 with musical guest Chris Stapleton.
