My favorite such trampoline is the "env" program.
As it says in the FreeBSD man page:

    "env" is sometimes useful with the ``#!'' construct (see execve(2)).
    The only difference between "#!/usr/local/bin/foo" and
    "#!/usr/bin/env /usr/local/bin/foo" is that the latter works
    even if /usr/local/bin/foo is itself interpreted.  Using "env"
    this way also allows one to reference "foo" without the path,
    as well as set up the environment as desired.
