Japanese Metal Gear Solid 2 Demo for PS2 - One of the guards says a Japanese phrase that sounds 100% exactly the same as "FUCK!". No joke, It's hilarious. You shoot him with the tranq gun to make em say it once in awhile.
Sims 1 for PC - When a sim is tired, they yell a phrase at you and then perform a "Butt Fucking" motion to the air. Who really does then when they're tired?
Sims 1 for PC - One of the adult male's phrases are "I'M SARN-A GAYN, BOO BOO BEE BEE!!!". This sounds very close to the phrase,"I'M SORT OF GAY, WOO HOO PEE PEE"
Grand Theft Auto 3 - When you pick up a prostitute and pay her for some "service"...You can switch to a front view to see that You and Her are mearly sitting there while the vehicle bumps up and down. Must be ONE HELL OF A HANDJOB!... (I havn't checked in Vice or SanAndreas, but it's probably the same.)
Tomb Raider 2: At Lara's house, that damn Butler follows you around everywhere!!! He even cuts a fart sometimes!!! Maybe he just wants a piece of ass.
Super Smash Brothers: Captain Falcon's ...FALCON KICK, when heard from a distance, sounds a lot like "Smokin Shit!" . Some guys were playing it at a party I was at a few years ago and we had 6 newcomers walk in the livingroom asking ,"Why does that guy keep smoking his shit..?"
