I thought lacrosse was what you find in la church.

The line is a bilingual pun built on the near-homophony between “lacrosse” (the sport) and the French phrase “la crosse,” which can mean a bishop’s crozier (a ceremonial staff) and, by extension, an object you might encounter in a church (“l’église”). Williams uses the joke to stage a comic misunderstanding: a speaker hears the name of a North American sport and reinterprets it through French vocabulary and Catholic imagery. The humor depends on cultural code-switching—French/English and secular/religious—typical of Williams’s rapid associative style, where wordplay becomes a way to expose how language shapes (and mis-shapes) meaning.
