Or, slightly bizarrely, just leave the -print off altogether - as the manpage 

    If none of -exec, -ls, -print0, or -ok is specified, the given
    expression shall be effectively replaced by ( given expression ) -print.

I forget where I saw this quote first, but the last five words always make me

    Real Programmers consider "what you see is what you get" to be just as
