Coronation Street actor Jack, who plays David Platt in the soap, sneakily added three unscripted lines into last night’s show.
The 30-year-old ad-libbed a line in three separate scenes in the hope it would make the final programme cut.
Cheekily, the soap star managed to get away with it, later posting a video clip to his social media accounts to reveal all.
In the first scene, Shona Ramsey (played by Julia Goulding) can be seen listening to David as he gasps: “I tell you. If I knew who did it. I mean, it’s just…”
A second scene includes Max Turner (Harry McDermott) with his stepfather David, saying: “Wait till I see Dev. I mean, it’s just…”
A third scene showed the character walking along the street raising his arms and saying: “I mean, it’s just…”
Taking to Instagram, Jack posted the short clip to his 245,000 followers.
The star captioned the clip: “If anybody noticed these ad libs tonight well done, they made me laugh at least. I mean, it’s just…”
He added on Twitter: “Love an add lib for my own amusement. I mean, it’s just….
“Massive ad lib, massively over top acting but funny.”
The short video is just eight seconds long but but has amassed more than 106,000 views on Instagram and another 101,000 on Twitter.
Fans instantly took to social media to reply to the clip.
One viewer tweeted: “@JackPShepherd88 David’s new catchphrase.”
“@JackPShepherd88 Must run in the family like the Audrey noise,” posted another.
A third said: “Made my week and killed my nostrils cause I laughed so hard while drinking xx.”
“@jackpshepherd88 I thought the bit were you were taking a sup of your drink through the straw in the restaurant was hilarious I was like it looks like he didn’t mean that and he’s giggling lol love it,” wrote another.
A fifth added: “Always enjoy your acting! We look forward to your genius delivery!”
Could this be the first David Platt blooper on the soap, or has actor Jack been spicing up his scenes with ad-libs for years?
Jack’s character has been through a rollercoaster year on the show after being drugged and raped by Josh Tucker (Ryan Clayton).
He went through a break-up with Shona following his harrowing ordeal, before the pair were open and settled their problems.
