Which detail from "Telephone Conversation" best contributes to its humorous tone?

1) "Madam," I warned, "I hate a wasted journey—I am African."

2) Silence. Silenced transmission of pressurized good breeding.

3) Red booth. Red pillar-box. Red double-tiered omnibus squelching tar.

3) "Facially, I am brunette, but madam, you should see the rest of me." ****

Is my answer correct?
