Quote #7
BENJAMIN: How did he do it? Did he get down on his knees? He didn't get down on his knees, I hope.
ELAINE: No, Benjamin.
BENJAMIN: Well, what did he say? I'm curious.
ELAINE: He said he thought we'd make a pretty good team.
BENJAMIN: Oh, no. He said that?
Ben thinks Carl's "pretty good team" line is ridiculous because it's utterly devoid of passion. Carl isn't desperately in love, he just wants someone he can reasonably function with (at least, that's how Ben sees it). It confirms Ben's idea of the staleness and emptiness of his parents' idea of marriage.
Quote #8
BENJAMIN: Do any of you fellows know where Carl Smith is?
FRAT BROTHER #1: He took off in the middle of the night to get married.
FRAT BROTHER #2: Probably one step ahead of the shotgun.
The frat brother's joke makes Carl sound like some sort of degenerate. (In case you don't know, a shotgun wedding is a wedding in which the groom has already gotten the bride pregnant—and hence is forced to marry her, gunpoint being the exaggerated reality of the coercion.) They already called Carl "the make-out king," so Ben is pretty protective of Elaine at this point. This exchange reminds us of how Mrs. Robinson got married because she was pregnant with Elaine.
