Help me ID this Star Wars qoute

Somewhere in the trilogy there is a qoute that goes something like this.

“Have you seen the new (IG88 or some similar Equipment designated)?”

I think it’s a stormtrooper who stays it but I’m not sure. It had no plot relevence at all, but I’m sure there’s a qoute like that somewhere in the trilogy.

Any Star Wars uber-geeks know where it is?

It’s when Obi-Wan is trying to sneak away after disabling the tractor beam on the Death Star.

Is is true they adlibbed that? I know the later lines (“Did you hear that?” “Eh, it’s just gas escaping”) sounded rather forced, like they had to really think about what to say. Any truth to the adlib rumor?

And my friend says she can see the tag on Carrie Fisher’s wig somewhere–I say it’s at least partially her hair to begin with. A little help?

Sorry for the hijack.

One great one is that Luke, jumping out of his X-wing, yells “Carrie!” instead of “Leia” in A New Hope.

All of the stormtroopers dialog was ‘looped’ (i.e. recorded later) so it can’t really be considered ad-libbed.

This has been debated ad nauseum. The general consensus is he’s just yelling, “Yeahhhhhh!”.

Well, I thought that was right, but all the scripts I’ve found don’t contain it, so I assume it was adlibbed.

“Eh, it’s just gas escaping”

Storm Trooper in-joke. Flatulence took a long time (sometimes up to 12 parsecs!) to escape the uniform, and always made a soft but unmistakable tweeet sound as it did.

And this long, tortured path that a fart had to take to escape a stormtrooper’s uniform was called the Kessel Run, right?
