“Abbott Elementary” star Quinta Brunson is hosting “Saturday Night Live” this weekend for the season finale with Benson Boone as musical guest. The promos for the show dropped yesterday and all three tease Boone’s flips. In the first one, that’s how he enters the frame. The third has cast member Sara Sherman “attempting” a flip off camera and then we see Sherman in a mangled heap on the ground. The finale means Colin Jost and Michael Che may be hilariously exchanging jokes again for “Weekend Update.”
