The title card for "Battle of the Band" appears in the style of the Beatles logo, and during the night of the talent show, Carl is given a makeover to resemble Ringo Starr, the former drummer of The Beatles, with the bowl-cut, glasses, and Scouse accent. Just like what The Beatles did in real life, the boys argue over their creative differences, leading to The Llama Lords of Science breaking up.
The melody and tune of the music that The Llama Lords of Science (Jimmy, Sheen, and Carl) play is similar to that of "Warning" by Green Day.
