Jimmy Fallon brings back his recurring "Ew!" bit, dressed in a purple dress and blonde wig as teen girl Sara, hosting a basement talk show. He welcomes his mom's friend's daughter Natalie, played by Taylor Swift in full nerdy gear—complete with oversized glasses, braces, pigtails, and a cat sweater. Swift leans completely into the awkward character, explaining her hobbies like collecting band-aids and building popsicle stick castles by herself. Things get ridiculous during Show and Tell around 02:12 when Natalie presents a glittery "pegacorn" drawing, only to accidentally sneeze snot all over it, prompting Fallon's signature "Ew!" reaction. Shortly after at 02:44, Sara starts dancing to Selena Gomez before being interrupted by stepdad Gary, who awkwardly sings Joan Osborne and breaks into a bizarre Shake 'n Bake dance.
The highlight of the sketch comes during the rapid-fire "Ew! Speed Round" starting around 03:36. Fallon holds up cue cards featuring random items like rice pudding, yield signs, and airplane mode, with both characters shouting "Ew!" in response. When a picture of a broken heart appears for "breaking up," Swift breaks out her iconic line, declaring they are "never ever ever ever getting back together," delivering a slick self-referential nod to her hit song. The contrast between her usual pop star image and this committed, goofy performance makes the sketch surprisingly entertaining.
