Samuel L. Jackson -- I'll Never Get Tired Of Motherf***ers!

As far as we know, Samuel L. Jackson isn't going for a record, but he might get it anyway ... because he LOVES sayin' motherf***er ... as much as he hates "these motherf***in' snakes!"

Jackson was leaving the "Today" show when our photog caught him throwin' out his favorite word at some autograph seekers ... lovingly, we think.

So we asked Sam how many MF missiles he fires a day, and the number is pretty high ... for the average person -- but kinda low for Jackson.

Don't worry though ... his motherf***ing total tally -- for LIFE -- is way more impressive. Do the math ... motherf***er!
