Some of my favorites:
Karen: What's that, honey?
Grace: Funnel cake
Karen: Can I have some?
Grace: Yeah, the stand is right over there...
Jack: Hey, friends, lovers, mothers and other strangers, you are not going to believe what just happened to me... Oh, my God, did you just see that? I almost did a half nelson, I almost bruised my delicates, my delicates, my domo arigatos, Mr tomatoes. Huge News! I have met, are you ready for this, Mr Right, well, Mr Right Now. Good night, folks, I'm here all week, Jack 2000. He works at the Jumpin Java - you know, the coffee shop on seventy second and his name is Paul and he is cute with a capital Q! And the busier it gets, the hotter he gets, and the hotter he gets the sweatier he gets, and the sweatier he gets... I forgot where I'm goin with this, but the main point is me likey he and he likey me and the best part of schezam, he gives me free iced coffee every time I go in which is every hour on the hour, good nights, and occasionally on the half hour. Ba ba ba ba ba
Jack: So we need to get them back together, but how? Pretend to think, pretend to think.
Karen: Pretend to care, pretend to care.
Jack: Oh, I've got it. What we need is a plan. Some way to get them in the same room together.
Karen: Oh honey, that's genius, write that down. Oh, wait, not on that, that's for Will and Grace, that's an invitation to Joe and Larry's kid's birthday party.
Jack: Oh yeah, I got one of these too. Anyway, enough about that. We have to figure out a way to get them in the same room so they can work it out. But how? Ow, I just got a paper cut on this party invitation for Will and Grace.
Karen: Focus. We're trying to get them in the same room together. Forget about this party they're both invited to. Now, what do they both like?
Jack: Well, Will likes to be taller than everyone, and Grace likes to eat cake.
Karen: Where can we take them where there'll be small people eating cake?
Karen: Oh, shoot, I just spilled on this invitation to a child's birthday party.
Karen: Hey, are you thinking what I'm thinking?
Jack: I don't know, are you thinking what it would be like to have Spiderman spray his web on you?
Karen: Okay that's just freaky.
Grace: Okay, here we go... that's weird. Will, what do you think is wrong?
Karen: Oh, my God. She just asked a Fairy an engine question. We're all gonna die in this car.
Greg: What did you do to me?
Grissom: You had a reaction.
Greg: I'm Hazmat meat. Quarantine, here I come.
Grissom: Your right foot, I swabbed with a placebo, regular tap water.
Greg: Yeah, well, I'm not worried about the right foot.
Grissom: Left foot...eumycotic dermatitis.
Greg: Oh, great. It's probably fatal.
Grissom: It's a mildew-induced skin rash.
Greg: You infected me with mildew?
Grissom: Here. Hydrocortisone. Follow the directions, clear it right up.
