How does Ben Stiller feel about Shaun White getting heat for an offensive Halloween costume based off his "Tropic Thunder" movie?
He's sorry. Still.
TMZ Sports broke the story ... White dressed up as "Simple Jack" -- a mentally disabled character who was constantly referred to as the R-word in the 2008 movie.
Back in 2008, several disability groups spoke out against the flick -- calling the Simple Jack character offensive and tasteless.
Now, with White trotting out the costume again, groups like the Special Olympics ripped Shaun for exploiting special needs for a cheap laugh.
