body: Legal texts - laws, contracts, etc - often contain passages that say something like, "You agree to waive your rights to blah except as prohibited by applicable laws or by the Whatshisface Amendment to the Something Act of 1985."
  
  
  What is the point of explicitly calling out the Whatshisface Amendment when it is clearly redundant after "applicable laws"?
