No way this would be allowed.
Maybe this has been discussed before, but I'm just to lazy to do a thorough search. Let's be realistic here. By that I mean, don't say "it's just a movie".
The part when Robbie is singing at the Bar Mitzvah. Robbie puts down the mic and George takes over the solo on the clarinet. Now, Robbie goes into the crowd and chooses a 13 year old girl for his dance partner. He then places her hands on his ass. That in itself may rise to a criminal act, if not, totally in appropriate. Lets be real; what parent would allow the lead singer of a band, a stranger no less, do that to there daughter? If that was my daughter, I would go out there an knock him right out! Does anyone agree?
