Song references. Sorry for imprecisions, I can't play right now to quote exactly...
but...
"It's the... urm... Knopfler transducer thingy..."
"What do you think this city has been built upon?" "Rock and Roll?" "I meant PIPES!"

When asking about Mrs. Piermont.
It was something like
"Shes usually around here with her dog. Shes the one with two legs."

when he's outside the surgery and he goes something like that, " i wouldn't show my butt if mine looks like that!"

"Do you have the BALLS?"
"THAT'S a sensitive subject"
ahahaha

When Ken's hand is stuck to the hand scanner:
"Maybe we can use this card...?"
"No, we can't."
"Yeah, I know."
Not exactly it but something like that. I was cracking up because I tried it accidently, when I clicked I thought "How the $%#& will that work?" lol

It's an ancient thread, but was anyone else expecting to see anything different on Lamb's "Pussy Parade" video tape? :D

I finally finished this game (the first time I played it was like 15 years ago!)

Pretty much any Foster-Joey dialogs are gold. When you ask Joey to jumpstart the robot at the beginning is priceless. Also:

Foster: Give me an analysis, Joey.
Joey: It's a standard 30mm steel wrench. And you can keep it away from my nuts.

I quite enjoyed the bits of dark dystopian humour, such as a Security Officer commenting about the helicopter crashing into the hospital, "It could have been worse. It could have hit the factory!" Also, the notice that while people with lower-level LINC status are reduced to rations, the higher ones simply have to do without croutons for a while (or something like that). Classic capitalism satire.

There are too many funny bits to choose just one, in my opinion! I think Lamb and Joey are especially funny.

The kitties video was the best "glance" of the future in the whole game. Haha,

Also Joey! or the "Teddy Bear" T-Shirt
