Finn Wolfhard kicked off his Saturday Night Live hosting debut with a Stranger Things cast reunion - and the tongue-in-cheek revelation that he's ready to do "adult films." "I know that a lot of people still see me as a kid but I'm 23 now. I'm proud to officially announce that I am a man," Wolfhard, 23, declared during his SNL monologue on Saturday, January 17. Wolfhard demonstrated his personal growth by having the SNL cameraman zoom in on his single facial hair, before he spit his first-ever taste of alcohol directly in cast member Marcello Hernández's face.
