One of Yankovic's recurring jokes involves the number 27. It is mentioned in the lyrics of several songs, and seen on the covers for Running with Scissors, Poodle Hat and Straight Outta Lynwood. He had originally just pulled the number 27 as a random figure to use in filling out lyrics, but as his fans started to notice the reuse of the number after the first few times, he began to purposely drop references to 27 within his lyrics, videos, and album covers. He explains that "It's just a number I started using that people started attaching a lot of importance to." Other recurring jokes revolve around the names Bob (the Al TV interviews often mention the name, David Bowe's character in UHF is named Bob, and a song called "Bob", done in the style of Bob Dylan, is featured on Poodle Hat), Frank (e.g. "Frank's 2000" TV"), and the surname "Finkelstein" (e.g. the music video for "I Lost on Jeopardy", or Fran Drescher's character, Pamela Finkelstein, in UHF). A number of songs use the phrase "internal organs". Also, a hamster called Harvey the Wonder Hamster is a recurring character in The Weird Al Show and the Al TV specials, as well as the subject of an original song on Alapalooza. Other recurring jokes include Yankovic borrowing or being owed, $5. In a number of  Al TV interviews, he often asks if he can borrow $5, being turned down every time. This motif also occurs in "Why Does This Always Happen to Me?", in which his deceased friend owes him $5. Another recurring joke is his attraction to female nostrils or nostrils in general. This also appears in numerous  Al TV interviews as well as in several of his songs ("Albuquerque" and "Wanna B Ur Lovr" to name a few.) Yankovic also asks his celebrity guests if they could "shave his back for a nickel". This also appears in the song "Albuquerque". Yankovic has also put two backmasking messages into his songs. The first, in "Nature Trail to Hell", said "Satan Eats Cheez Whiz"; the second, in "I Remember Larry", said "Wow, you must have an awful lot of free time on your hands."
