The swear-happy actor and producer, 71, is offering to teach an epic, multi-language course on the art of cursing if enough people double-check that they’re registered to vote.

“Listen up — if 2,500 of you click a voting action below to make sure you’re #GoodToVote, I will teach you to swear in 15 different languages,” Jackson tweeted Monday along with a clip of him in a sweatshirt and baseball cap while seated in an expensive-looking armchair.

The tweet also includes a link to his page on voter registration website HeadCount, which includes a sultry-looking photo of Jackson along with patriotically colored buttons offering Americans the ability to register to vote, check their registration status and “make your vote plan.”

Jackson is well-known for being among the Hollywood actors with the most prolifically dirty onscreen mouths — although a survey conducted earlier this year found that “The Wolf of Wall Street” star Jonah Hill beat Jackson for the top slot. While Jackson has sworn onscreen 301 times in his career, Hill has sworn 376 — mostly in the record-breakingly swear-heavy Scorsese flick.

In addition to cussing onscreen and using obscenities to encourage Americans to vote, Jackson also gave a profane PSA back in April. “Stay the f–k home,” the “Pulp Fiction” actor said during an appearance on “Jimmy Kimmel Live!” in response to quarantine orders designed to help flatten the curve of the COVID-19 pandemic.

He also riffed on the book “Go the F–k to Sleep” during the appearance, presenting the 2011 kids bedtime story as a public order that people should not leave their homes, including the verse:

Stay the f–k at home
Corona is spreading; this s–t is no joke
It’s no time to work or roam
The way you can fight it is simple, my friends
Just stay the f–k at home
