Vince Vaughn -- It's a Small World, After All ... Which Sucks When You're 6'5" (PHOTO)

Vince Vaughn stuffed his ginormous frame into the rides at Disneyland Tuesday as he enjoyed a day in the amusement park with his family.

These photos are way more adorable than the new season of "True Detective" -- though Vince has got a better shot at turning that around ... than squeezing into the damn Tea Cups ride.
