Get the Bruce Forsything mug.
While constipated and sitting on the toilet straining, you may find yourself with your fist pressed up against your forehead, and a gurning expression on your face. This level of constipation is termed a "Bruce Forsyth". You will resemble a pose made famous by a popular UK entertainer Bruce Forsyth, which he would perform not long after appearing in front of an audience.
