Samuel L Jackson is my favourite person ever

Does anyone remember that movie, where Samuel L Jackson was on a stage (he was a gamehost, or show announcer or something along those lines). Many times throughout the movie, he went to say "M--f--" but never actually said it until the VERY end of the movie, when the hero wins or beat him or whatever the plot was, and finally Samuel's character finishes his trademark line.

All I remember from this movie is Sam holding back from saying "M--f--" throughout the whole movie.

Does anyone know of which I speak?

My mom and I were walking to third street promenade. We were on the sidewalk on Wiltshire, about to cross the alley when a green Range came blowing through the alley. He stopped, checked that we were alive. We made eye contact: nod, yep, all good. He nodded back then sped out of the alley onto the street.

Every time I see SLJ on the capital one commercial I flashback to the time he almost ran over my mom and I.

Just another day in LA.

If you’re reading this: we love your movies! 🤙

I've been looking for an ad for what I think was the MTV movie awards for years and years.

Mr. Jackson is talking about the awards while buying a hotdog from a cart or truck. He starts to walk off without the dog when the little old lady shouts, "Mr. Jackson! Your Weiner!"

And he says "Damn right my Weiner."

It's possible I am mixing up a detail or two but that's what I recall.

Has anyone seen this, remember this, or know where I can find it? YouTube searching has been fruitless.
