Yuki Midorikawa, creator of Natsume Yuujinchou, drew this image. <--Lies!
Not being bilingual, I can't be 100% certain that this is Wodehouse-inspired. However, Hyperwords translated the caption above the image as Katsuta sentence (melody “please, [jivusu]”) from message. Perhaps "Jivusu" is the equivalent of Jeeves?
