Duke Nukem Forever/Funny

""Hell, I'd still hit it.""
 * I vote for the "interactive" dildo in This video.
 * Duke: You wanna touch it, don't you?
 * Upon seeing a giant three-breasted alien monstrosity, most people would probably run and hide. Duke's response?

"Duke: Combo! Double Combo! Triple Combo! Super Combo!"
 * "Yeah, but after 12 fucking years it should be."
 * When Gearbox had to delay the game again by one month, to June 10th in Europe and June 14th in the US, Gearbox released this video announcing the delay, with the Tagline "Duke never comes early."
 * This new trailer really puts strain on the definition of "Mature humor"

"Soldier: Why didn't we think of that!? WHHHHHYYYYYYYYY!?"
 * And yes, there's an achievement/trophy tied into finding and stealing a piece of poo. Behold, the Turd Burglar.
 * During a point in the demo, Duke is allowed to draw a 'plan' on a whiteboard for some soldiers. No matter how nonsensical a drawing you make or how much of the original plan you replace, the soldier observing will respond with amazement.

"Soldier: I have no idea what that means, but if I did, I bet that guy over there would still have his arm. And at least one ball."
 * Alternately:

"Beep beep, motherfucker! Frickin' jaywalkers. So much for anti-lock brakes."
 * Running an enemy over with Duke's monster truck:

""Hey, kid. I'm not a toy. I'm an action figure!""
 * When Duke gets shrunk by a trap in "The Lady Killer" he meets a kid who says he's "the coolest toy ever." Duke's response?

""Now those were some rodents of unusual size.""
 * Later, while shrunk, Duke ends up fighting some rats who mistake him for an easy meal.

"If you die by falling off a ledge, it's really just your own fault. When getting shot at, avoid bullets.
 * Hearing shrunken Duke exclaim "motherfucker!!!" in his squeaky voice as he falls down an air vent.
 * Upon being first shrunk; "The fuck...?"
 * The text on the loading screen offers some hilarious commentary as well.

If you get stuck, you can always cheat by reading an online FAQ.

Picking up a turd in a toilet won't lower Ego, but we really wanted it to.

You can slap our wall boobs, since real girls don't like it when you slap theirs"

"General Graves: America is counting on you. Duke: [singing] America, fuck yeah!"
 * For the Interactive Achievement 2011 Awards, Gearbox made this video. And it is HILARIOUS!
 * Duke's gleeful cackle and mimicking of complex machinery winding down broken after he trashes a turbine in "Underground" was so unexpected yet appropriate, it got this troper giggling for the remainder of the level. Also, he has never felt so good about vandalism before.
 * Near the end of the game:

"Duke Clone: Repeat after me. I've got balls balls balls balls of steel. Duke: I've got balls...er...balls, balls, balls of steel?"
 * Punching out Christian Bale. Nothing more needs to be said.
 * In The Doctor Who Cloned Me,  becomes one of the funniest parts of series.   best line is   idea to get Duke   (reverse the polarity) and the follow-up. It's just how proud  sounds about the idea that sells it.
 * Voice verification.
