Salman Khan bites the inauguration ribbon

Salman Khan recently tried to use his mouth to cut an inauguration ribbon at the inauguration of World Gym at Thane. This is a photo....of him doing this in the presence of Minister R.R. Patil..... who is trying to cut the ribbon with a scissor. I wonder what prompted this ? Did the minister have rusted scissors ...or is Salman trying to prove that he uses Colgate toothpaste or Dabur Danth Manjan....hmmm maybe it Salman Khan's bad sense of humour once again.
