This cake I'd heard of, first through The Simpsons:
Agnes: [to Bart, who is keeping her busy whilst Seymour and Edna sneak out] I collect pictures of wedding cakes from different periods. (She opens a book containing photographs of cakes) It all started in 1969 when Good Housekeeping featured a picture of a lovely cake.
Bart: You wouldn't happen to have any real cakes around here, would you?
Agnes: Oh my, no. Don't care for cake, too sweet. (points at a cake) Now, this is called a Lady Baltimore cake. At my age, I don't have that much saliva left, so you'll have to lick my thumb before I turn the page.
Bart: Aw, can't I just turn the page for you?
Agnes: [slaps his hand away, harsher] No! [sweetly] But you can pick out any picture you want to take home with you.
Bart: Erm...O.K. I'll take...that one.
Agnes: [slaps his hand away] NO!
Bart: Aah! What the-
Agnes: You can't have that one: that's a coconut cake!
