Two men are out ice fishing at their favourite fishing hole, just fishing quietly and drinking beer. Almost silently, so as not to scare the fish, Rick says, "I think I'm going to divorce my wife - she hasn't spoken to me in over 2 months."
Dave continues slowly sipping his beer, then thoughtfully says, "You better think it over - women like that are hard to find."
