Lee Mack's stand-up routine on Riverdance is a classic bit of fast-paced physical comedy. He opens by mimicking the stiff-upper-body posture of Irish dancing, joking that the performers look like someone constantly checking the bottoms of their shoes to see if they've stepped in dog mess. He goes on to describe buying cheap ten-pound tickets to see a live show in London, only to find himself sitting so far back and low down that he could only see the dancers from the waist up. Watching two hours of motionless upper bodies while fast tap-shoe sound effects echo across the stage forms the hilarious centerpiece of the joke (0:50).
The routine then pivots to a story about visiting a nightclub in Dublin, where he tries out a cheesy pick-up line about an electrician, only to get brutally shot down before attempting his waist-up Riverdance moves on the dance floor. Mack's frantic energy, quick physical gags, and sharp self-deprecation keep the audience laughing throughout the brief clip. It is a fantastic reminder of why his live stand-up routines remain so popular.
