Bad Moon Rising - S4.E22

Ray's attempts to alleviate Debra's PMS moodiness only make her more irritable. When Ray witnesses Debra's hypersensitive mood and generally annoyed reaction to everything he says and does, he checks the calendar and realizes it's going to be a long couple of days ahead. In his desire to get a ""quick fix"" for Debra's womanly problems – thus making his life a heck of a lot easier – he turns a bad situation worse by suggesting that a simple pill will help with his wife's insufferable mood swings.
