Jay Leno made his return to "The Tonight Show" following his departure earlier this year. The former host has been featured in different sketches since Jimmy Fallon took over, but this was his first guest appearance on set.
Fallon seemed genuinely thrilled to have Leno on the show and started off the interview by earnestly asking, "How am I doing?"
Check out Leno's answer in the video above. Boy, that crisp autumn air really is something though, right?
"The Tonight Show Starring Jimmy Fallon" airs weeknights at 11:35 p.m. ET on NBC.
