There’s no way to confirm this, but at this point we’re convinced that if Samuel L. Jackson signs on for an R-rated movie (and the occasional PG-13 movie), it’s stated in his contract that there must be at least one “motherfucker” written into the script. Or, in the case of Jackie Brown, 37 instances of Jackson’s famous catchphrase.

In all, Jackson has uttered “motherfucker” 171 times (in 27 films), with more than half coming from the aforementioned Jackie Brown, along with Pulp Fiction and Soul Men. In case you’re wondering where the rest came from, The Huffington Post provided a full breakdown of Jackson’s motherfuckin’ filmography:
