In the segment, the ponytail is revealed to basically be Grande's assistant, picking up the phone for her, autographing an album for a fan, and getting Fallon a drink from the fridge. For the grand finale, the ponytail even fights crime, tripping a guy who just mugged a woman in Fallon's office. (Might want to look into upping that security detail, J?) It's also quite polite, offering a deep-throated "You're welcome" after being thanked by the woman whose purse he just recovered. (Oh and, yes, the ponytail appears to be a man — because feminism.)
