Samuel L. Jackson

Golf keeps coming up in Donald Trump's presidential campaign, but his golf etiquette took a big hit this week.

Samuel L. Jackson, in an interview with Rhapsody, alleged that he got a bill from Trump National Golf Club, despite not being a member. Jackson posted the bill to Instagram (it has since been deleted).

Jackson claimed to have played golf with Trump, who he said is more "P.T. Barnum than politician." Jackson refused to pay the surprising bill.

Trump wouldn't take the criticism.

In stepped actor Anthony Anderson to try to jog Trump's memory:

That's a scene: Trump, Jackson and Anderson knocking back some shrimp and hot dogs after 18 holes.

Jackson was a guest on Late Night with Seth Meyers Tuesday. Meyers "informed" Jackson he is in a feud with Trump, to which Jackson scoffed. Jackson told the same story as Anderson, going on to explain a moment in which Trump cheated.

"We clearly saw him hook a ball into a lake at Trump National in Jersey," Jackson said. "And his caddy told him, 'We found it.'" Jackson said the caddy was not wet, and Trump went on to play like he was not tilting his score.

Jackson also told a story in which he was called up by Trump, who referred to himself as, "The Don," to set up a round with Bill Clinton. Trump did not play, but he met Jackson and Clinton in the middle of the round and gave Clinton a jacket "because he was a little chilly." Jackson insists Clinton can connect Jackson to Trump.

On Wednesday, Trump responded:

One minute Trump doesn't know Samuel L. Jackson, the next he judges the actor's golf swing. Something doesn't add up.

Meyers told Jackson, "If we can prove that Donald Trump is lying when he says he doesn't know you, this might be the thing that finally brings down his campaign."

Jackson responded, "Let's get on that."

Trump, who believes Bernie Sanders threatens golf in the U.S., has been hitting most of the fairways on his campaign. But this week, he found the rough.
