It's Prime Minister's Questions, which gives MPs a weekly chance to pick a comfortable seat, jeer at their opponents, and occasionally ask David Cameron a question.
So we decided to slide into the Twitter DMs of three MPs during Wednesday's PMQs.
The brave volunteers were Louise Haigh, Labour MP for Sheffield Heeley; Jamie Reed, Labour MP for Copeland; and Stewart McDonald, SNP MP for Glasgow South. (We asked some Conservative MPs but they declined to take part.)
