Artists like to see their fans STANDING during their concerts.  But is it a crime if they stay seated?  And should the artist call them out if they do?

Madonna tried that the other night and it backfired spectacularly.

During her show in Inglewood, California on Thursday, she saw a fan in her seat and said, quote, “What are you doing sitting down over there?”

But when she went to the edge of the stage to investigate, she realized the fan was in a WHEELCHAIR.

She said, quote, “Oh, okay.  Politically incorrect.  Sorry about that.  I’m glad you are here.”  (Here’s video.)
