Quote #4
…and somewhere, somewhere in the back of that pea-sized brain of hers, an organ developed just enough to let her eat, drink, and emit, she has some foul parody of sexual desire. And I, Peter, I am the object of her sweaty lust. (142)
Just about all we know about Jerry's landlady is that she's disgusting and she lusts after Jerry. If you haven't noticed, in this play lust is often disgusting or dirty. Why might that be?
Quote #5
But I have found a way to keep her off…I merely say: but Love; wasn't yesterday enough for you, and the day before? (144)
Jerry tricks the landlady into thinking she has slept with him. We know what you're thinking: how? We wish we knew, too. Either way, it's interesting to notice that the fantasy of sleeping with him substitutes for the reality, kind of like how the playing cards are a substitute for sex. Sex—it's tricky.
Quote #6
I do believe it's an old dog…it's certainly a misused one…almost always has an erection…of sorts. That's red, too. (157)
A dog with a giant red erection. Sex is absurd and animal and ugly. And remember the dog keeps attacking Jerry; the relationship between him and the dog seems like it is supposed to be sexual (at least from the dog's perspective), just like the relation with Peter is almost sexual at times.
