Ours is even when he is here.
I think the answer to your question is:
The current shell reads the first line of an executable script, and finding
the sharp-bang, interprets what follows as the name of the "shell" to
called to run the rest of the script.
If what follows the sharp-bang is not the name of a "shell" the line
is interpretd as a comment, as lines beginning with a sharp are supposed
to be.
The seems to be some disagreement as to whether white-space between the
bang and the shell name causes the line to be taken to be a comment or
not.
You didn't ask, but I'll tell you that if the "shell" takes command-line
arguments, anything to the right of the shell-name will be passed as
command-line arguments.
