In the Merv Griffen Set, they cut the first bumper with Kramer and Jerry walking down the street. (I don't have the entire exchange, but they cut it all!)
K: ...But when he took this special formula he became Mr. Abel.
J: You broke my blender, didn't you?
K: Yeah, well I was trying to make gravel, and it just -- just didn't work out.
J: I knew it!
And in "The Slicer," they cut the whole beginning bumper off too! This cut is really bad, it contains one of the best "Shut up. You shut up" exchanges!
[Elaine is in bed with Jerry; she rolls over and says:]
Elaine: Hey.
Jerry: Morning
Elaine: This is crazy, you know, I, ah, I can't go on like this.
Jerry: But why?
Elaine: I need some space. [Rolls over, sees George on the other side of the bed]
George: Does that mean I have to go too?
Jerry: Hey, well you don't think she's just talking to me
George: Hey. Shut up!
Jerry: You shut up!
Elaine: I hate this.
[Kramer sneaks up from under the covers]
Kramer: You'll get used to it. It's like a rugby scrum.
Elaine: No no, I don't want this anymore.
Jerry: We're going to work with you.
George: And on your dates.
Jerry: And shopping
Kramer: And to the bathroom.
[Jerry, George & Kramer]: Elaine. Elaine.
Elaine: I can't breathe.
[Jerry, George & Kramer]: Elaine. Elaine.
Elaine: I'm suffocating.
[Jerry, George & Kramer]: Elaine. Elaine.
Elaine: I can't breathe.
[Waking up, sitting upright in bed] Elaine: You're all killing me!
[Elaine hears alarm buzzing, checks her clock and it's not ringing, pounds on the wall behind her head board.]
Elaine: "Turn your alarm off!
[Wraps pillow around her head] Elaine: Ahhhhhhhhhh!
They cut the whole thing! The scene of all four of them in bed is grotesquely funny.
