Matt Lucas is filling in for a missing baker in one of the episodes. He said: "I was forced to bake by my bosses at the last minute when one of the bakers became unavailable. I can't tell you how happy I was that my humiliation was caught on camera."
Stand Up To Cancer was launched in 2012 and is a joint national fundraising campaign from Cancer Research UK and Channel 4.
