Michael Rosen, a British author and poet, became an unlikely meme star after filmed performances of his children's poems spread on YouTube in the late 2000s. Editors remixed his facial expressions, clicks and pauses into countless parodies. Skype, once the default video calling app, had an equally recognisable ringtone for a generation of internet users. Combining the two tapped into shared nostalgia, and the mashup circulated on soundboards and in meme edits where Rosen's earnest delivery could be dropped into any fake call scenario.
