"Clooney as the Bat" is about how Michael Keaton and Val Kilmer were ultimately outshined by the villains in Batman (1989), Batman Returns and Batman Forever. Batman & Robin is presented as George Clooney to succeed where Keaton and Kilmer failed, but "Clooney struck out like the rest." The parody also mentions how the first three movies were technically three strikes, but the narrator points out that this isn't a baseball game.
Another parody does this with The Death of Superman, positing that Superman "took a dive" against Doomsday due to other heroes overshadowing him and his movie sequels doing poorly.
Yet another parody does this with Howard Stern, but unlike most, the ending doesn't imply that he failed; instead, it says he made a show that's even grosser than his competition.
Garfield and Friends: In the U.S. Acres segment, "Orson at the Bat", Orson gets knocked out during a baseball game he and his friends have and has a dream where he is Casey of Casey at the Bat fame.
Tiny Toon Adventures: The first segment of "Son of the Wacko World of Sports", "Buster at the Bat", is a parody of the poem, featuring the show's cast as a baseball team and Buster in the role of Casey. The segment ends with Buster getting a home run and winning the game, much to the surprise of Sylvester, who reminds him that's not the way the poem is supposed to go. Buster's response is "You were expecting me to strike out? I'm the star of this show!"
