Great British Bake Off 2015: Best innuendos of all-time... from 'perfect nuts' to 'erect biscuits'

Hurry home to catch the next batch of dirty jokes on BBC1 tonight

Judge Mary Berry may look the picture of innocence as she ices her buns, complains about soggy bottoms and sings The Sound of Music, but much of her critique (about a contestant's "perfect nuts" and so forth...) had Twitter going wild last series, and we can expect more of the same this time around.
