I saw a disco/funk band in the 80s in Liverpool. The dance floor was empty so the singer shouts out, “Come on folks let’s see you all up on the dance floor!”. So, one guy gets up and starts dancing in the middle of the dance floor, at which point the singer goes back to the mic and says, “Not like that mate, you look a c**t!”
Harsh, I know, but flawless timing.
