The star has also revealed he injured his back during rehearsals. Speaking on his podcast, The Useless Hotline Podcast, he said: "I had a pinched nerve all week in my back. I had acupuncture."
But he was still able to perform on Saturday night and has been back to his intense rehearsal schedule this week.
Mr Clarke said he was always a "massive YouTube fan" and he first started sharing content online while at university.
He said he avoids labelling his content comedy, but instead calls it "an attempt at entertaining".
His videos of situational comedy and point-of-view clips has since amassed millions of followers across TikTok, YouTube and Instagram, with his podcast The Useless Hotline which he co-hosts with Max Baledge, also charting number one in the UK.
