The comment is called a hashbang or shebang.  It tells the kernel which program 
to start.  Your script is passed over stdin to the interpreter.

Note that on many system /bin/sh is a symlink to bash, so interpreting your 
code with /bin/sh would just start the bash interpreter in POSIXLY_CORRECT mode.
