We don't know about you, but we've been watching with much amusement as Calum Best attempts to remain celibate for 50 days and nights. OK, so 50 days isn't that long, but let's not forget that sex to Calum Best is like eating for most people – it's a necessity of his life. For the latest stage in his quest to keep little Calum in his pants, the ladies' man has agreed to take part in a lie detector test. Rigged up to a computer, Calum is told there is "no way" he will be able to beat the machine. There then follows some rather uncomfortable questioning (more for us than for him) before the results are revealed. Do you think he's managed to keep it zipped up? Why not watch the clip and find out.
