What film contains the quote "He's going in there...I wouldn't."

possible different spelling: "He's goin' in there...I wouldn't"

HeHe... One of my favorites if we are thinking of the same thing.

"He's going down there. I wouldn't"

Quote by Barf the Mog (half Man half Dog) from the movie Spaceballs.
Mog's character is played by the late John Candy

Scene takes place near the end of the movie as Lone Starr (Bill
Pullman) exits the ship down a ladder to face Dark Helmet (Rick
Moranis) and destroy MegaMaid.

A funny movie every time... Hope its the same thing you were thinking of.

this is precisely the line I was looking for, thanks
