Although according to POSIX 
  Enclosing characters in single-quotes ( '' ) shall preserve the literal
  value of each character within the single-quotes. A single-quote cannot
  occur within single-quotes.

so "!" should be not treated as special character in POSIX shell, csh unfortunately does not follow this. Try

  $ echo '!!'
in csh, tcsh (now that's funny) and bash (or dash).
