Fern Brady's Snort, Raspberry, Whistle (with original subtitles)
I'm sure the captioning professional had a good day transcribing this scene.
The subtitles are from the Channel 4 broadcast. On YouTube, series 12 through 14 on YouTube have a different set of subtitles which, while hugely appreciated, aren't quite as colourful and expressive as the original ones. From series 15 onwards, the YouTube subtitles are identical to the Channel 4/Red Bee Media ones.
