Kuroshitsuji (Black Butler)
Cannon, no. Fanfiction and fanart, possibly and yes.
He made Undertaker laugh and it's unknown as to how he did.

Sebastian Michaelis is the 'black butler' in the Anime/Manga Black Butler/Kuroshitsuji. In short, he is a demon that was contracted to the young Earl Ciel Phantomhive; to help fulfill the boy's wish for revenge in exchange for his soul.
She is hired by the Phantomhive manor to work as its maid, and to act as a protector of the manor its self, and a bodyguard to Ciel when Sebastian is otherwise indisposed.
Sebastian Michaelis is introduced by first and last name in the Kuroshitsuji Manga: chapter 1, page 10. The characters around him do not say his last name there, but the announcement of it as a 'tag' is made.
