Quote #4
Want it or not, he can't ignore that call.
Sexual obsession has him in its thrall. (2.4.191-192)
Mrs. Peachum sings about Mac's fatal flaw, his incapacity to resist the hookers. She calls him "sexually obsessed," and that inability to "ignore" the call reminds us of that scene with the sirens in the Odyssey. It's beyond his control.
Quote #5
LUCY. I hear you have a lovely ankle
And I'd love to see such a complete tart.They tell me that Mac says your behind is so provoking.
POLLY. Did he know, did he now?
LUCY. If what I see is true he must be joking. (2.6.145-151)
Inspiring Mac's lust becomes an Olympic event when Polly and Lucy start competing for his attention. Rather than being offended by his lecherous attention, the girls strive for it, comparing behinds and ankles. Mac reduces them to body parts, and sadly they accept their role.
Quote #6
JENNY. And if our friend Suky Tawdry isn't here with us now, it's because he went on from me to her to console her too. (3.7.59-61)
Well, we never. Mac is just a scandal. He busts out of jail and goes straight to Jenny, one prostitute. Then, from her place he moves on to yet another hooker, Suky Tawdry (whose name, by the way, is killer). Mac's seemingly insatiable appetite for women is, in a word, lust.
