How about "Selling for Husband"?
Ad goes something like this:
"Husband hid a Ef 80-200mm F2.8 lens from me and didn't get my approval to buy it. Now I've found out I want to sell this lens to punish him on top of the 1-month sleeping on couch for him. All reasonable offers will be considered. Please let your wife know you're buying this lens as husband sleeping on couch is not good for both especially for the wife as she needs loving and warmth more and she doesn't have Nikon, Canon or Leica to play with."
