Actor Varun Dhawan shared a hilarious gym video with YouTuber-comedian Samay Raina while promoting Hai Jawani Toh Ishq Hona Hai. As Varun recited lines from the film's song Wow, Samay roasted the track, saying, "Aise nahi chalega gaana. Accha gaana banao apne aap chalega." Varun's reaction left fans and filmmaker Karan Johar laughing in the comments section of the video.
