How do I answer the question, "When are you having kids?"?

Now that this spinster has finally tied the knot (I’m 30) to my very fabulous, former long-term boyfriend; I’m very often asked the question, “When are you guys/y’all (he’s from TX) going to have kids?” There seems to be no answer that will prevent the inevitable, “You guys bettter hurry. You’re not getting any younger!” (He’s 35.) So I have grown tired of being polite about this very, in my opinion, impolite question. So give me your best, snottiest, snarkiest responses!
