I’m surprised Slate’s piece on Britney’s use of puns in her latest single didn’t include a mention of Duchamp’s L.H.O.O.Q.
“If U Seek Amy” (say it three times fast):
“L.H.O.O.Q.” (say it three times fast in French with slang in mind—nevermind: it sounds like “elle a chaud au cul,” i.e., “she’s horny”):
Fitting?
