The Eurovision Song Contest is an international song competition, organised annually by the European Broadcasting Union (EBU) and featuring participants representing primarily European countries. Each participating country submits an original song to be performed on live television and radio, transmitted to national broadcasters via the EBU's Eurovision and Euroradio networks, with competing countries then casting votes for the other countries' songs to determine the winner.
Ten Dutch celebrities participate in each broadcast. Two non-ordinary questions are asked of the Dutch celebrities per episode, such as "Who would have the easiest time going forty days without sex?", "Who used to be chosen last in gymnastics?" and "Who is your best friend?". The broadcasts claim that for each question a panel of 100 people compiled in advance a top 10 in which the famous candidates were "ranked."
