Harlan Ellison and Stan Lee voice their own characters in The Simpsons episode “Married to the Blob,” airing Sunday, January 12.

Here is a synopsis of the story:

Comic Book Guy realizes his comics are nothing if he can’t share them with anyone. Then he meets Kumiko, a Japanese woman writing an autobiographical manga, and he seeks out Homer’s advice on how to date her, ending happily for everyone.

Ellison said earlier this year he appears in a scene with show characters Milhouse and the Comic Book Guy.

Stan Lee, reports Entertainment Weekly, “swings by Comic Book Guy’s store and doles out some advice on comics, romance, and, yes, romance comics”.
