Crocodiles optional?

… the only hammer in the house belongs to Tony, and for anything other than simple nail-pounding she looks in the Yellow Pages. Why risk your life? … She has never seen the point of lawns. Given the choice she’d prefer a moat, with a drawbridge, and crocodiles optional.

No deep wisdom here perhaps, but I can relate to these lines from Margaret Atwood’s novel The Robber Bride. There are days though when crocodiles are a must!
