Ever seen a 7'3" NBA center jam himself into a tiny-ass sports car???
Now you have ... 'cause Kristaps Porzingis shoved his giant frame into what appears to be a Tesla Roadster on Monday night -- and the video is hilarious!!!
The Dallas Mavericks superstar was out with teammates Luka Doncic and Jalen Brunson -- when hilarity ensued at a valet stand.
A tiny electric car pulled up ... and for some reason, Kristaps poured himself into it -- and everyone who was watching could not stop laughing.
Porzingis' knees were jammed up near his throat .
