The Great British Bake Off returned last night for a very special cause.

The beloved baking series aired the first of its Stand Up To Cancer episodes on Tuesday, which proved to (almost) be a huge hit with viewers. But there was one moment in particular that people weren't a huge fan of - and it involves Mary Berry. The GBBO legend left the series alongside Sue Perkins and Mel Giedroyc after opting not to move from the BBC to Channel 4. She got a shout out on the series this week when Paul Hollywood and Prue Leith judged Harry Hill's cupcakes, each of which contained a message hidden inside. https://twitter.com/RyanJL/status/971119432574689281 After the judges complimented his bake, host Sandi Toksvig asked if they could "read another fortune." She opened up and burst into laughter as she read what was written. When asked by Paul what it said, she replied:

"A copy of Mary Berry's birth certificate."

And while everyone on the show laughed at the quip, people watching at home didn't find it as amusing. Plenty of viewers appreciated the nod to Mary, with one person saying their "Bake Off has been made" by the reference. https://twitter.com/scottygb/status/971118283150778368 https://twitter.com/its_reecehs/status/971118947381768192 https://twitter.com/MollyScottxx/status/971118204788584448 Others, however, were far less impressed. https://twitter.com/suewhittaker1/status/971120952133275650 https://twitter.com/reallyreally_/status/971120958596636673 https://twitter.com/g_leigh1/status/971140930802733057 https://twitter.com/RBlackBT/status/971118493159575552 The comedian was joined by BBC Breakfast’s Bill Turnbull, Roisin Conaty, and actor Martin Kemp in the first instalment of the celebrity series.
