Check out SnoopCard.com. You can call any number and tell the system what incorrect/phony/whatever incoming number to display on the receiving phone's caller id. You can call suspected OM's number "from" your wife's number and see what kind of greeting you get ("Hi, sexy!"). Conversely, you can call your wife's phone "from" suspected OM's phone number and see how she answers ("Hello there, stud").
They even give you a free trial call. And you can get the free trial call every time you log onto the site (therefore virtually unlimited "free" calls without subscribing to the service).
