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).
