"Keep your wife or girlfriend on her toes by mentioning the names of other women when pretending to sleep."
I'd advise against that one! A girlfriend many years ago used to call me by her previous boyfriend's name at least once a day. It didn't bother me at first but after a while I began to find it irritating so I decided to try
User1314's technique to get my own back. The next thing I knew, I'd been elbowed in the solar plexus and shoved out of bed
! She wouldn't speak to me for a couple of days, despite me pointing out that she did it to me all the time...
