The Pearls Before Swine strip of 4/21 has cartoonist Stephan Pastis committing a formula pun joke, a genre of humor at which he’s a master:
(#1) Pig assembles, for Goat as his straight man, the parts of an outrageous pun on the first two lines of the Beatles’ song “Something”: Something in the way she moves / Attracts me like no other lover (and then in the last, frame-breaking, panel, Goat upbraids Pastis for exploiting him for the sake of a joke)
So, two things: formula pun jokes; and the song “Something”.
Formula pun jokes. From my 12/2/23 posting “Sense-shifting pun jokes”, which are
of two types, the second of which is the formula pun joke: a set-up + pay-off story based on a formulaic expression, the parts of which are assembled in the telling of the story (by “accreting the components of the monstrously complex result”, as I put it in a posting on a wonderful example from a Pearls Before Swine strip:
(#2) The “Force Cor” joke (again, Pig is the joke-teller and Goat the straight man, and it’s Rat who upbraids Pastis in the last panel)
The Beatles song. From Wikipedia:
“Something” is a song by the English rock band the Beatles from their eleventh studio album Abbey Road (1969). It was written by George Harrison, the band’s lead guitarist. Together with his second contribution to Abbey Road, “Here Comes the Sun”, it is widely viewed by music historians as having marked Harrison’s ascendancy as a composer to the level of the Beatles’ principal songwriters, John Lennon and Paul McCartney.
